नेपालमा आयुर्वेदको चमत्कार: सात दिनमै निको भए कोरोना सङ्क्रमित

2020-08-16T17:27:00.000+05:45

काठमाडौँ- आयुर्वेद चिकित्साप्रति मानिसको विश्वास गुमिरहेको समयमा कोरोना सङ्क्रमण भएका बिरामीलाई भने आयुर्वेदिक औषधिले फाइदा गरेको छ ।

कीर्तिपुरस्थित आयुर्वेद अनुसन्धान तथा तालिम केन्द्रमा भर्ना भएका कोरोना सङ्क्रमित ३३ जना सात दिनमै निको भएर घर गएका छन् । अरु पनि निको भएर जाने क्रम बढ्दो छ ।

आयुर्वेद अनुसन्धान अस्पतालका अनुसन्धान अधिकृत डा. अमितमान जोशी भन्छन, ‘आयुर्वेदिक औषधिमा विभिन्न रोगप्रतिरोध क्षमता बढाउने जडीबुटीको प्रयोग हुने भएको कारण कोरोनासँग लड्न सक्ने क्षमता चाँडो विकास भई निको भएको हो ।’

उनका अनुसार कोरोना सङ्क्रमणका कारण भर्ना भएपछि आयुर्वेद विज्ञ चिकित्सक टोलीबीच छलफल गरी श्वासप्रश्वाससम्बन्धी रोगमा प्रयोग हुने र रोग प्रतिरोधी क्षमता बढाउने जडीबुटी मिलाएर बनाइएको औषधि सेवन गर्न दिइएको थियो । त्यसको सात दिनपछि पीसीआर परीक्षण गराउँदा सबैको रिपोर्ट नेगेटिभ आएको डा.जोशीले जानकारी दिए ।

कोरोना स’ङ्क्र’मण पुष्टि भएपछि भक्तपुरकी २२ वर्षीय नर्स कीर्तिपुरस्थित आयुर्वेद अनुसन्धान अस्पतालमा भर्ना भईन । आफूले बिरामीलाई एलोपेथिक औषधिमात्र सेवन गर्न दिने गर्ने गरको उनले कहिले पनि आयुर्वेदिक औषधि प्रयोग गरेकी थिइनन् । आयुर्वेदिक चिकि’त्सकहरूको सल्लाहबमोजिम सोही औषधि से”वन गरको र अहिले आफूलाई समस्या नभएको बताइन ।

आफू १० दिनमा डिस्चार्ज भएको जानकारी दिँदै दैनिक तीन पटक दुई वटा औषधि खाएकाे र त्यसैले काेरोनालाई सजिलै जित्न सकेकाे उनले बताइन । ‘अहिलेसम्म पनि कुनै पनि नराकात्मक असर देखा परेको छैन भने मैले आफ्नो नर्सको ड्युटी पनि समालिसकेको छु ।’ उनले भनिन ।

उनीमात्र होइन बाग्लुङका ३५ वर्षीय जङ्गबहादुर केसीलाई पनि कोरोनालाई जित्न आयुर्वेदिक औषधिले धेरै मद्दत गरेको बताउँछन । कतारबाट नेपाल आएका केसी भक्तपुरस्थित राधेराधेमा होल्डिङ सेन्टरमा बसेपछि पीसीआर टेस्ट गराउँदा पोजिटिभ देखेको थियो । खासै कुनै कोरोनाको लक्षण नदेखिएको र उनले अस्पतालमा हुँदा तातो पानीमा बेसार र नुन हालेर दैनिक रुपमा खान्थे ।

केसी भन्छन, ‘अस्पतालको व्यवस्था धेरै राम्रो छ । कोठा तातो पानीको व्यवस्था थियो र दैनिक रोग प्रतिरोधात्मक शक्ति बढाउने आयुर्वेदिक औषधि दिनको तीन पटक खान दिन्थ्यो ।’ आठ दिनमा नै कोरोनाको रिपोर्ट नेगेटिभ आएपछि घर फर्केको जानकारी दिँदै थपे, ‘हाल हर्बल चिया र चेवनप्रासको सेवन गरिरहेको छु । अहिले म आफूलाई स्वस्थ्य र बलियो पनि महसुस गरिराखेको छु ।’

गत असार २५ र २६ गते भर्ना भएका उनीहरू एक हप्तामै डिस्चार्ज भएको अस्पतालले जनाइएको छ । डा. जोशीले पहिलोपटक भर्ना भएका २० जना कोरोना सङक्रमित व्यक्तिहरू सबै डिस्चार्ज भएकाे बताए । त्यसलगत्तै दोस्रोपटक पनि २० जना भर्ना भएकाे थियाे । जसमा १४ जना डिस्चार्ज भइसकेको जानकारी दिए ।

आयुर्वेद अनुसन्धान तथा तालिम केन्द्रका चिकित्सक तथा कोभिड-१९ का संयोजक डा. जितेन्द्र श्रेष्ठले हाल अस्पतालमा १६७ जना रहेको जानकारी दिँदै थपे, ‘पुरुष १२१ र महिला ४७ जना उपाचारमा रहेका छन् । उनीहरूलाई पनि सोही औषधिको प्रयोग गरिरहेका छाैँ । सबैको अवस्था सामान्य नै रहेको छ ।’

अहिलेसम्म दुई जनालाई ग’ङ्गालाल अस्पताल र एक जनालाई आइसियुको लागि टेकु पठाइएको उनले बताए ।भर्ना भएकामध्ये तीन जनामा मात्र सामान्य रुघाखोकी, श्वा’स फेर्न गाह्रो हुने र ज्वरो आउनेजस्ता मध्यम लक्षण देखिएका थिए भने अरूमा खासै लक्षण नदेखिएकाे डा. श्रेष्ठले जानकारी दिए।

उनका अनुसार भर्ना भएका सबैलाई स्वस्थ पार्ने विषयमा केन्द्रका विज्ञ चिकित्सकबीच छलफल गरी स’ङ्क्र’मितलाई विभिन्न आयुर्वेदिक औषधि दिइएको हो ।
टोलीमा काया चिकित्सक, पोषणविद्, द्र’व्यगुण चिकि’त्सक, शल्यविज्ञलगायत मिलेर औषधि छनोट गरिएको थियो । डा. जोशीले स’ङ्क्र’मितलाई शरीरको प्रतिरक्षा शक्ति बढाउन गुर्जो, पिप्ला, अ’श्वग’न्धा, तुलसी सुतमनी, मरिजलगायत जडीबुटीबाट बनेको औषधि खुवाइएको जानकारी दिए।

औषधिका साथै खानामा पनि ध्यान दिएको प्रष्ट पार्दै उनले भने, ‘कोरोना स’ङ्क्र’मणलाई भिटामिन सी, खनिजमा जि’ङक र सेलेनियम भएको त्यसै अनुसारको खाना मिलाएर दिने गरेका छौँ ।’ डा. श्रेष्ठ भने खाना र औषधिको साथै मेडिटेसन, सामान्य नाचगान तथा योगा गर्नको लागि मौखिक रुपमा जानकारी दिइएकाे यलु जोशीले गोरखापत्र अनलाईनमा लेखेका छन् ।

Science Give reason Question and answer class 10 pressure

2020-08-03T18:00:00.000+05:45

Chapter : 2 Pressure All Give reason question answer:

Give reason question and ans:

1. Why do sea drivers wear well designed suits?

As the depth of the sea increases, the pressure increases since pressure increases with depth. The pressure exerted by water deep under the sea is much greater than at the sea level. Hence, the deep sea divers wear special suits which protect them from extreme pressure of water. These suits are called diving suits. These suits contain buoyancy compensators to combat the weight of their diving equipment and the pressure of water at great depths.

2. A bucket is filled faster at the lower stairs than at the upper stairs. why?

We can fill a bucket from downstairs tap quicker than from an upstairs tap because due to gravitational Force the water exerts more pressure in downstairs tap as compared to upstairs tap. The water will come out of tap with a great force of pressure.

Or,

We know that the liquid pressure is directly proportional to the depth or height, For top stair depth is low and for upstairs depth or height is high so more pressure is applied to it and more force is applied therefore A bucket is filled faster at the lower stairs than at the upper stairs.

3. The blood pressure in humans is greater at the feet than at the brain

The pressure of a liquid is given by the relation:

P = hdg

Where,

P = Pressure

h = Height of the liquid column

d = Density of the liquid

g = Acceleration due to the gravity

It can be inferred that pressure is directly proportional to height. Hence, the blood pressure in human vessels depends on the height of the blood column in the body. The height of the blood column is more at the feet than it is at the brain. Hence, the blood pressure at the feet is more than it is at the brain.

4. An egg floats on salty water but sink in pure water. why?

Because the density of the egg is higher than the density of tap water, so it sinks, When enough salt is added to the water, the saltwater solution's density becomes higher, if density is increased then Upthrust is high, so the egg will be float.

5. An iron nail sinks in water but a ship made of iron floats.

It’s because an iron ship is not completely solid. It has full of air filled in it. So the average density of the ship as a whole is less than the density of water. Therefore immersed portion of the ship displaces water equal to its weight. So the ship floats whereas a sheet of iron is compact and there are no air spaces inside it. Iron is denser than that of water. The weight of the sheet is greater than the weight of the water displaced by the sheet. So it sinks.

6. Why water pump cannot lift water more than 10 meters high from the earth surface?

Because a water pump is based on the principle of atmospheric pressure. Atmospheric pressure cannot push up water up to 10 metre high. At above 10 m atmospheric pressure is become low. So, water pump cannot lift water more than 10 meters high

7. Why can water not be used in barometric liquid?

water cannot be used as barometric liquid because it's density is lower than Mercury .water's density is 1000 gram per cubic meter.hence it requires a barometer whose height is around 11 meters.

8. The bottom of dam is wider and stronger than upper part.OR Walls of a dam are made thicker at the bottom. Why?

Liquid pressure is directly proportional to the depth of liquid from free surface. At the bottom of dam, there is high water pressure. To protect the dam from the high water pressure, the bottom is made wide and stronger than the upper part.

9. The pressure exerted by water at the bottom of the drum decreases slightly at the Himalayan region than that in the Terai region.

Since pressure of a liquid is directly proportional to the value of g and the value of g is more at Terai region than that in the Himalayan region. So, the pressure exerted by water at the bottom of the drum decreases slightly at the Himalayan region than that in the Terai region.

10. The bucket filled faster in the downstairs tap than in upstairs tap.

Pressure of a liquid is directly proportional to its depth or height from the free surface. The tap at the downstairs is at greater height than the tap at the upstairs. Water comes out with greater pressure from the downstairs tap. So, bucket is filled faster in the downstairs tap than in upstairs tap.

11. The speed of flow of water out of a tap of upper floor is less than that of the down floor.

Since pressure of a liquid is directly proportional to its depth or height from the free surface. The height of the liquid column on the down floor is more than that on the upper floor. So the speed flow of water out of a tap of upper floor is less than that of the down floor.

12. A deep sea-diver needs to wear diving suit.

The pressure of a liquid is directly proportional to the height of liquid column from free surface. When a person dives deep into sea, he or she has to bear high water pressure. To withstand with high water pressure, it is necessary to wear diving suit.

13. Weight of stone decreases in the salt solution.

When salt is dissolved in water, the upthrust increases due to the increases in the density of water . As a result, the weight of a stone decreases in the salt solution.

14. It is easier to lift a heavy stone inside the water.

The weight of the stone inside the water decreases due to the upthrust. So it is easier to lift a heavy stone inside the water.

15. The weight of a body is lighter in water than in air.

Upthrust due to water is greater than that of air. Upthrust decreases weight of body. Hence, the weight of a body is lighter in water than in air.

16. The weight of a body is more in vacuum than in air.

There is no upthrust in vacuum. Upthrust decreases the weight of body. Hence, the weight of body is less in air due to its upthrust.

17. It is easier to pull a bucket of water from the well until it is inside the water but difficult when it is out of water.

Upthrust due to water is greater than that of air. Upthrust exerted by water decreases weight of body. Hence, it is easier to pull a bucket of water from the well until it is inside the water but difficult when it is out of water.

18. Studs are made on the sole of football player’s boot.

P = F/A

Studs are made on the sole of football player’s boot to increase the pressure on the ground that prevents the player from falling or sliding during sudden run and turning.

19. It is easier to cut vegetables with the sharp-edged knife than the blunt one.

The area of the edge of sharp knife is less than that of the blunt one. So sharp-edged knife can exert more pressure while applying force than that of the blunt edged knife as the pressure is inversely proportional to the area. Due to more pressure, it is easier to cut vegetables with the sharp-edged knife than the blunt one.

20. Buses and trucks have broad and double wheeled tyres.

The buses and trucks have to carry greater weight which exerts greater pressure on the tyres. The pressure on them is reduces by increasing the area of the tyres as the pressure is inversely proportional to the area.

21. Camel can walk easily on sand.

Camel has flat-soled feet which exert less pressure due to the body weight of camel. As there is less pressure exerted by flat-soled feet of camel, it can easily walk on the sand.

22. The wheel of tractor is wider than that of a car.

The rear wheels of a tractor are made large and flat to reduce the pressure and prevent the tyres from descending into the muddy land. As tractor is used for ploughing and threshing in crop fields, small and narrow real wheels may descent into the muddy and marshy load due to more pressure.

23. The water supply tanks are placed higher than any other building in a town.

The water supply tanks are placed higher than any other building in a town so that the pressure of water is more. Due to this, water can flow to the buildings located at higher level. As a result, water can be supplied easily on the taps of uppermost floors and houses built at higher level of ground.

24. The gravity bulb of hydrometer is made heavier.

The gravity bulb of hydrometer is made heavier so that its centre of gravity remains very low, when it is floating in denser liquids. It helps the hydrometer to float upright in stable equilibrium.

25. Hydrometer has a heavy bulb and narrow stem.

Hydrometer has a heavy bulb to float in a liquid vertically. The stem of hydrometer is made long and narrow to find the relative density of less dense liquid i.e. it increase its sensitivity.

26. The floatation bulb (buoyancy bulb) of hydrometer is made small.

The floatation bulb of hydrometer is made small because denser liquids provide more upthrust and hence the whole hydrometer does not float on the dense liquid.

27. An egg sinks in fresh water but floats in a strong solution of salt (or in a saturated salt solution).

Fresh water has less density than that of the egg so the egg cannot displace water equal to its weight and it sinks. But salt on mixing with water increases the density of water which increase upthrust and hence the egg can displace water equal to its weight and floats.

28. Iceberg made up of water floats in water.

The density of ice is less than that of water. Due to this, iceberg is able to displace the water equal to its weight. Hence, Iceberg made up of water floats in water.

29. An iron nail sinks in water but a ship made up of iron floats.

Since the density of iron is greater than that of water, the iron nail sinks as the weight of the nail is greater than the weight of the displaced water. But the ship made of up iron is designed in such a way that the relative density of ship becomes always less than that of water. Hence, the weight of water displaced becomes equal to the total weight of the ship and the ship floats.

30. It is easier for a man to swim in sea water than in river water.

The density of sea water is more than that of river water. Thus for the same volume, the sea water provides more upthrust as compared to the river water. So it is easier for a man to swim in sea water than in river water.

31. A hole at the bottom of a boat is more dangerous than that at the side.

The bottom of the boat exerts more pressure, as the force acts perpendicularly downwards, than that at the sides. If there is hole at the bottom of the boat, more water enters inside due to more upthrust and the boat may sink. So, a hole at the bottom of a boat is more dangerous than that at the side.

32. An iron nail sinks in water but floats in mercury.

The density of iron is more than that of the water. The iron nail cannot displace the eater equal to its weight and it sink. But the density of mercury is much more than that of the water. It gives more upthrust which helps the iron nail to float on mercury.

33. A girl with heeled shoe exerts a higher pressure on the ground than an elephant.

The area of the heels of the girl’s shoes is much smaller in comparison with the area covered by the flat feet of the elephant. As a girl with heeled shoe exerts a higher pressure on the ground than an elephant.

34. A man exerts more pressure under his foot when he stands with one foot than when he stands on two feet.

The area of one foot is less than that of two feet. As so a man exerts more pressure under his foot when he stands with one foot than when he stands on two feet.

35. The base of the house is made wider than its wall.

The walls and roof of house exerts pressure on the base of a house. The pressure exerted by the building is reduced by making the base of the house wider as pressure is inversely proportional to the area.

36. The loaded ship sinks more than empty ship.

The loaded ship has larger mass. Hence, the weight (or volume) of displaced water is more for loaded ship. But the empty ship has lesser mass. Hence, the weight (or volume) of displaced water is less for empty ship. So the loaded ship sinks more than empty ship.

Please download the pdf by clicking the top of the pop-up and read it A stone is tied to the middle of a string and suspended from one end as shown in the given figure. Here S is the stone and O is the point of suspension. If you give a sharp jerk at P, the string will break : ANS: When you give a quick downward jerk to the bottom string, you exceed the breaking tension in the bottom string in such a short time that, because of the inertia of the stone, you cannot accelerate it significantly, and the tension in the top string does not increase significantly above initial value..Therefore, the bottom string breaks, and the stone remains hanging from the top string.

What are metalliods? Name any 3 metalliods.

Elements which lie between metal and nonmetal of the periodic table and possess both the metallic and non metallic character are called metalliods.

Silicon (Si), germanium (Ge), and bismuth
(Bi)

Why the elements of group IA are called alkali metal?

The metallic oxide of the metal of group IA dissolves in water to form alkali. So they are called alkali metal.

Why the elements of group IIA are called alkali earth metal?

The metallic oxide of the metal of group IA dissolves in water to form alkali, further their oxides and carbonates are abundantly present on the earth crust. So they are called alkali earth metal.

Why the properties of elements of one group of periodic table are similar?

Elements of same group of periodic table contains same number of electrons in the outer most orbits of their atoms due to similar electronic configuration. Therefore they have similar chemical and physical properties.

Why the properties of the elements of different group of periodic table are different?

Elements of different group of periodic table contain different number of electrons in the outer most orbit of their atom. Therefore they have different chemical and physical properties.

Why the properties of the elements of different group of periodic table are different?

Elements of diffrent group of periodic table contain different number of electrons in the outer most orbit of their atom. Therefore they have different chemical and physical properties because these electrons are responsible to take part in the chemical reaction.

Why the elements of group IA of periodic table are known as highly reactive metals?

Except hydrogen; lithium, sodium, potassium etc. of first group of periodic table are metals. They have only one electron in the outermost orbit of the atoms. So they react easily and quickly with other elements by the donation of one electron of their outermost orbits.Therefore they are called highly reactive metals.

Why the elements of group VIIA of periodic table are known as highly reactive nonmetal?

Fluorine,chlorine,bromine,iodine etc.of group -VII of periodic table are nonmetals and their atoms contain 7 electrons in the outermost orbit. So they react easily and quickly with other elements by sharing electrons or by accepting one electron. Therefore the elements of group VII of periodic table is known as highly reactive nonmetals.

Why the elements of group '0'of periodic table are knows as insert gases?

Helium,Neon, Argon, Krypton etc. of 'Group-0' of the periodic table are gases. Their outermost orbit is fulfilled with the electrons either by 8 electrons (octet) or by 2 electrons (duplet).Since an element takes part in chemical reaction to complete the number of electrons in their outer most orbits,therefore they do not react with other elements and are known as insert gas.

Write down characteristics of modern (new)periodic table.

1. Elements are divided into 9 groups (18 columns ) and 7 periods (rows).

2. Landthanides and actinides are placed differently at the bottom of the periodic table.

3. Elements are divided not only into the groups and periods but they are also divided into 4 distinct blocks i.e.s,p,d and f-block elements.

4. Elements of Gr-VIII of old periodic table like Fe,Co,Ni,etc.are taken as transition elements and are placed in the order of transition elements between Gr.II A and IIIA.

5. Elements are arranged in the order of their increasing atomic number from left to right of the table.

What are representative elements?

Elements of group -IA,IIA,IIIA,IVA,VA,and VIIA are called representative elements in which the outerost orbit of the atoms are not fullfilled with the number of electrons. They are s-block and p-block elements except noble gasses.

_{Why hydrogen is placed in group IA of periodic table?}

Like Li,Na,K etc of Gr-I of periodic table, hydrogen also reacts with halogens (flurione,chlorine etc) as an electropositive elements .

Hydrogen can be placed in group VIIA of periodic table?Why?

Following are the reasons:

i) It is a gas at the ordinary temperature like some halogens of group -VIIA of periodic table.

ii) Like halogens,its molecule its diatomic.

iii) Metals form halides with the halogens like NaCl,KBr etc .and similarly some metals form hydrides with hydrogen e.g. NaH,KH,CaH₂etc.

iv) If it were placed in 'Group-VIIA'' there would not be a blank space for six elements between hydrogen and helium.

Why the elements of Group-VIIA of periodic table are known as halogens.

'Hale' means 'sea-salts' and 'genes' means 'produce'. So, halogen means sea-salt producer.This name is given to the elements of Gr-VIIA (F,Cl,Br etc.) of periodic table because chlorine produce sea-salt i.e. sodium chloride and other elements have also the tendency to form salts.

Why ''Alkali metals'' are placed in 'Group-IA' of periodic table.What is transition element?

The elemlent which lies in between highly reactive metals and nonmetals i.e. from group IIIB to IIB of periodic table are called transition elements.

Why transition metals have variable valency?

In case of transition metals,both the outermost and inner shells are not f'ulfilled with the electrons.Some times, only the electrons of the outermost orbit and some times the electrons of the inner orbit also take part in chemical reaction so their valency differ according to the number of electron that take part in chemical reaction.

What are landthanides and actinides?

After the element Lanthanum (At.No.-57), a series of 14 elements i.e. 'Cerium'(At.No.-58) to Lutetium (At.No.-71) and after Actinium (At.No.-89) another series of 14 elements i.e.Thorium (At.No.-90) to Lawrencium(At.No.-103) are called landthanides and Actinides respectively.

( In both the series their f-sub shell is being filled with electrons so they are knowns as f-block elements and are placed at the bottom of the periodic table. They are also known as inner transition element.)

What are duplet and octet?

The condition of the elements having capacity to hold maximum two electrons in the outermost orbit of its atom is known as duplet.

The condition of the element having capacity to hold maximum eight electrons in the outermost orbit of its atom is known as octet.

What do you mean by 2n²rule of electron configuration?

It is a rule that gives the maximum number of electrons that an orbit of the atom can hold. Here 'n' represents number of orbit. According to this rule first orbit, 2nd orbit and 3rd orbit can hold 2,8,and 18 electrons respectively.

First orbit (n=1)

2n²= 2*1²=2*1=2

Second orbit (n=2)

2n²=2*2²=2*4=8

Write down the maximum number of electron that can stay in s,p,d and f sub-shells.

sub-shell No.Of electrons

s 2

p 6

d 10

f 14

Why landthanide and actinide are placed in different place in modern periodic table?

They have totally different properties than other elements of periodic table. They are characterized by the electrons being filled up in 'f ' orbital of forth orbit in case of Landthaide and 'f ' orbital of fith orbit in case of Actinides. Their property depends upon the number of electrons in 'f ' orbital. Therefore they are kept differently than other elements i.e. at the bottom of the periodic table.

What is s-block and p-block element?

Elements in which last electron enters into the s-sub shell of the outermost shell of their atom is called s-block element. Elements of group IA and IIA are s-block element.

Elements in which last electron enters into the p-sub shell of the outermost shell of their atom is called p-block element. Elements of group IIIA,IVA,VA,VIA,VIIA and '0' are called p-block element.

What are d-block and f-block element?

Elements in which the last electron enters into d-sub shell of their penultimate shell are called d-block elements. Elements of group IIIB,IVB,VB,VIB,VIIB,IB and IIB are d-block elements.

Elements in which the last electron enters into f-sub shell of their anti-penultimate shell are called f-block element. Landthanides and actinides are f-block element.

Write down any two differences between s-block and p-block element.

s-block element	p-block element
1) Last electron enters into s-sub shell of their atom.	1) Last electron enters into p-sub shell of thier atom.
2) They lie in group-IA &IIA of periodic table.	2) They lie in group IIIA,IVA,VA,VIA,VIIA and 0 of periodic table.

Write down any three differences between d-block and f-block element.

d-block element	f-block element
1) Last electron enters into d-sub shell of penultimate shell.	1) Last electron enters into f-sub shell of antepenultimate shell.
2) They are arranged in the middle part of the periodic table.	2) They are placed at the bottom part of the periodic table.
3) They are comaparatively more in number than f-block element.	3) They are only 28 which are comparatively less than d-block element.

What is Aufbau principle?

This principle expresses how electrons are filled in different sub shell. According to this principle, electrons are filled in the sub shell from lower energy level to higher energy level. And the order of filling of sub shell is represented by following way:

What is noble gas?

Elements of 'Group 0' of periodic table i.e helium, neon, argon, krypton, xenon and radon are called noble gases because their outermost orbit is fulfilled with number of electrons either by eight electrons (octet) or by two electrons (duplet). So they do not take part in the chemical reaction and are called noble (or inert)gases.

What are halogens?

Elements of 'GroupVII A' of periodic table are called halogens. They are fluorine, chlorine, bromine, iodine etc.

How are elements arranged in modern periodic table?

In modern periodic table, elements are arranged in the increasing order of atomic number from left to right in such a way that the elements having similar electronic configuration are in the same group.

What do you mean by metallic and non-metallic character of an element in a chemical reaction?

If an element reacts with another by donating electron then that character is called metallic character, but if it gains electrons then it is called non-metallic character.

What would be the effect on metallic character:

i) As we move from left to right in a period of periodic table.

When we move in a period from left to right, atomic radius goes on decreasing from 'Group-I' to 'Group-VII'. If an atom has greater radius, the attraction between the proton and the electron of outermost orbit becomes less. So, in a chemical reaction, the tendency to lose the electron/ s from the outermost orbit of the atom decreases. Tendency of loss of electron is metallic character. Therefore, metallic character gradually decreases due to the decrease of atomic radius as we move from left to right in a period.

ii) When we move down in a group of P.T.

As we move down in a periodic table, atomic radius of elements gradually increases due to the increase in number of orbits. Now the force of attraction between the proton and the electrons of the outermost orbit decreases . So they tendency of losing electrons in the chemical reactions i.e. the metallic characteristic increases.

The Earth in the Universe

The Earth is egg shape.

Constellatio:

Constellatio are the group of stars having fixed shapes. Examples: Aries, Cancer, Aquarius, Leo, Libra etc.

Galaxy is the system of stars that consists star, star clusters, dust and gases held together by gravity.

Solar system is composed of the sun, eight planets including the earth, satellites, asteroids, comets, meteorites etc. The distance in the space is measured in the term of light year.

Planets are the heavenly bodies which revolve around the sun in elliptical path without being intersected by path of other planets.

There are major eight planets in the solar system. They are: Mercury Venus Earth Mars Jupiter, Saturn, Uranus and Neptune.

The closest planet and the farthest planet from the sun is mercury and Neptune respectively

Mercury is the fast rotating planet. Venus is the brightest planet. Mars is red planet. Jupiter is the largest planet. Earth is the only one planet where the life is possible.

Motion of earth

The earth revolves around the sun which is called revolution of the earth. The revolution of the earth causes the changes in the season. Earth takes 365.5 days to complete one rotation. It also rotates about its own axis which causes the change in day and night. To complete its one rotation about its own axis, it takes 23 hours 50 minutes and 4 sec.

Eclipses

When the earth comes in between the sun and the moon and they lie in a straight line, the shadow of the moon falls on the moon. At this stage, we cannot see the moon and this phenomenon is known as lunar eclipse.

The solar eclipse occurs when the moon comes in between the earth and the sun and in a straight line and the shadow of the moon falls on the surface of the earth.

Classification-of-Elements-and-Periodicity

2019-12-14T21:01:00.000+05:45

Atomic ModelClick Here

Name some elements whose atomic weight was corrected by the arrangement of the elements in the Mendeleev's periodic table.

Gold (Au), platinum (Pt), Aluminium (AI) etc.

Write down the defect of Mendeleev's periodic table?

i) Anomalous position of hydrogen: Hydrogen is placed with alkali metals in group-I but it is non-metal and its property is similar to the halogens of group-VII.

ii) Anomalous pair of elements: Some elements having higher atomic weight precede the elements with lower atomic weight. For example Ar (Atomic weight 39.9) precedes K (Atomic weight 39.1). Similarly Co (Atomic weight 58.9) precedes Ni (Atomic weight 58.7)

iii) Position of isotope: If periodic table was made according to the increasing order of atomic weight then isotope should also have had position in the periodic table.

iv) Some dissimilar elements were placed together but some similar elements were placed in different group. For example CU, AG, AU etc. are placed in group I with alkali metals like Li, Na, k etc. But similar elements like Cu and Hg were placed in different group i.e. Group I and II respectively.

v) Position of lanthanides and actinides: There wasn't any place for lanthanides and actinides.

vi) Position of elements of group VIII was not clear because nine elements of group VIII were placed in the form of triad without any justification.

Write down modern periodic law.

The physical and chemical properties of elements are a periodic function of their atomic number.

Note: Mosley suggested that atomic number should be the basis of the classification after his one of the important experiments. He found that when high speed electron strikes a metal, x-ray produces. The frequency of x-ray depends upon atomic number of metal. So he suggested that atomic number should be the basis of classification.

Write down the difference between old periodic table and modern periodic table.

They are N, O, F, P, S, Cl, Se, Br, I, At (Astatine) and 'o' Group elements.

What are metalloids? Name any 3 metalloids.

Elements which lie between metal and non-metal of the periodic table and possess both the metallic and non-metallic character are called metalloids.

Silicon (Si), germanium (Ge), and bismuth
(Bi)

Why the elements of group IA are called alkali metal?

The metallic oxide of the metal of group IA dissolves in water to form alkali. So they are called alkali metal.

Why the elements of group IIA are called alkali earth metal?

The metallic oxide of the metal of group IA dissolves in water to form alkali, further their oxides and carbonates are abundantly present on the earth crust. So they are called alkali earth metal.

Why the properties of elements of one group of periodic table are similar?

Why the properties of the elements of different group of periodic table are different?

Elements of different group of periodic table contain different number of electrons in the outer most orbit of their atom. Therefore they have different chemical and physical properties.

Why the properties of the elements of different group of periodic table are different?

Elements of different group of periodic table contain different number of electrons in the outer most orbit of their atom. Therefore they have different chemical and physical properties because these electrons are responsible to take part in the chemical reaction.

Why the elements of group IA of periodic table are known as highly reactive metals?

Why the elements of group VIIA of periodic table are known as highly reactive non-metal?

Fluorine, chlorine, bromine, iodine etc. of group -VII of periodic table are non-metals and their atoms contain 7 electrons in the outermost orbit. So they react easily and quickly with other elements by sharing electrons or by accepting one electron. Therefore the elements of group VII of periodic table is known as highly reactive non-metals.

Why the elements of group '0'of periodic table are knows as insert gases?

Helium, Neon, Argon, Krypton etc. of 'Group-0' of the periodic table are gases. Their outermost orbit is fulfilled with the electrons either by 8 electrons (octet) or by 2 electrons (duple).Since an element takes part in chemical reaction to complete the number of electrons in their outer most orbits, therefore they do not react with other elements and are known as insert gas.

Write down characteristics of modern (new) periodic table.

1. Elements are divided into 9 groups (18 columns) and 7 periods (rows).

2. Lanthanides and actinides are placed differently at the bottom of the periodic table.

3. Elements are divided not only into the groups and periods but they are also divided into 4 distinct blocks i.e. s, p, d and f-block elements.

4. Elements of Gr-VIII of old periodic table like Fe, Co, Ni, etc. are taken as transition elements and are placed in the order of transition elements between Gr. II A and IIIA.

5. Elements are arranged in the order of their increasing atomic number from left to right of the table.

What are representative elements?

Elements of group -IA, IIA, IIIA, IVA, VA, and VIIA are called representative elements in which the outermost orbit of the atoms are not fulfilled with the number of electrons. They are s-block and p-block elements except noble gasses.

_{Why hydrogen is placed in group IA of periodic table?}

Like Li, Na, K etc. of Gr-I of periodic table, hydrogen also reacts with halogens (fluorine, chlorine etc.) as an electropositive elements.

Hydrogen can be placed in group VIIA of periodic table? Why?

Following are the reasons:

i) It is a gas at the ordinary temperature like some halogens of group -VIIA of periodic table.

ii) Like halogens, its molecule it's diatomic.

iii) Metals form halides with the halogens like NaCl, KBr etc. and similarly some metals form hydrides with hydrogen e.g. NaH,KH,CaH₂etc.

iv) If it were placed in 'Group-VIIA'' there would not be a blank space for six elements between hydrogen and helium.

Why the elements of Group-VIIA of periodic table are known as halogens.

'Hale' means 'sea-salts' and 'genes' means 'produce'. So, halogen means sea-salt producer. This name is given to the elements of Gr-VIIA (F, Cl, Br etc.) of periodic table because chlorine produce sea-salt i.e. sodium chloride and other elements have also the tendency to form salts.

Why ''Alkali metals'' are placed in 'Group-IA' of periodic table.

Because alkali metals contain one electron in their outermost orbit. They can easily remove their valence electron and they form salt combining with VIIIA group elements.

What is transition element?

The element which lies in between highly reactive metals and non-metals i.e. from group IIIB to IIB of periodic table are called transition elements.

Why transition metals have variable valency?

In case of transition metals, both the outermost and inner shells are not fulfilled with the electrons. Sometimes, only the electrons of the outermost orbit and sometimes the electrons of the inner orbit also take part in chemical reaction so their valency differ according to the number of electron that take part in chemical reaction.

What are lanthanides and actinides?

After the element Lanthanum (At.No.-57), a series of 14 elements i.e. 'Cerium'(At.No.-58) to Lutetium (At.No.-71) and after Actinium (At.No.-89) another series of 14 elements i.e. Thorium (At.No.-90) to Lawrencium (At.No.-103) are called lanthanides and Actinides respectively.

(In both the series their f-sub shell is being filled with electrons so they are knowns as f-block elements and are placed at the bottom of the periodic table. They are also known as inner transition element.)

What are duplet and octet?

The condition of the elements having capacity to hold maximum two electrons in the outermost orbit of its atom is known as duplet.

The condition of the element having capacity to hold maximum eight electrons in the outermost orbit of its atom is known as octet.

What do you mean by 2n²rule of electron configuration?

First orbit (n=1)

2n²= 2*1²=2*1=2

Second orbit (n=2)

2n²=2*2²=2*4=8

Classification of Elements Chemistry Problem solution:

some Important question and answer of the chemistry classification of elements. On the Basis of the CBSE and SEC exam.

Modern Periodic Table

What is periodic table?

It is a table of elements that contains all elements in the order of increasing atomic number in such a away that the elements having similar physical and chemical properties are kept in one group.

What is group of the periodic table?

The elements that form a vertical column of periodic table and having similar physical and chemical properties are known as groups of periodic table.[Note: There are 9 groups in periodic table]

Write down full form of IUPAC. How elements are classified into groups according to IUPAC system?

Full form IUPAC is International Union of Pure and Applied Chemistry. According to IUPAC,each vertical column of elements is taken as group. So elements are classified into 18 groups i.e. from 'Group- 1' to 'Group-18.

How the groups of element are made in modern periodic table?Write down the name of the group.

In modern periodic table,element are classified into 9 groups.

They are IA,IIA,IIIB,IVB,VB,VIIB,IB,IIB, IIIA, IVA, VA, VIA, VIIA and 0. IA to VIIA and IB to VIIA i.e. combining group A and group there are 7 groups moreover group VIII and 0 when there are altogether 9 groups.

What is the periodic of the periodic table?

The elements that form a horizontal row of periodic table are known as period of the periodic table.

What do you mean by very short, short, long and very long period of the periodic table?

Periods 1 of the periodic table is called very short period because it contains only two elements i.e. Hydrogen and Helium. Period 2 and 3 of the periodic table are called short period because each of them contains 8 elements. Period 4 and 5 of the periodic are called long period because they contain 18 elements in each of them. Sixth period of the periodic table is called the very long period because it contains 32 elements.

Write down any two advantages of periodic table.

i) It makes the study of the elements short providing the group study of the elements.

ii) Properties of different elements can be comparatively studied by the group comparison of the elements.

What do you mean by the word ''periodic' of the periodic table?

Periodic means the order of the definite number of elements in a regular interval.

Write down the real name of the following elements named by Mendeleev.

i) Eka- Aluminium ii) Eka-Born iii) Eka-Silicon iv) Eka-Manganese

i) Eka-Aluminium is Gallium.

ii)Eka-Boron is Scandium

iii) Eka-Silicon is Germanium

iv) Eka- Manganese is Technetium.

How was elements arranged in old periodic table made by Mendeleev?

Mendeleev arranged elements in the increasing order of atomic weight from left to right of the periodic table.

Write down Mendeleev's periodic law with its meaning.

The physical and chemical properties of the elements are the periodic function of their atomic weight. It means if elements are arranged in the order of their increasing atomic weight, elements with similar properties are repeated after certain regular interval.

Write down the importance of Mendeleev's periodic table?

The importance of Mendeleev's periodic table is:

i) Systematic study of element: It simplified and systematised the study of elements and their compounds.

ii) Prediction of new elements: Some elements were not discovered at the time of Mendeleev. While making table of elements, he left a space for those elements and predicated that they will be discovered in future. That encouraged the scientist to discover them later. For example, Gallium and Geranium were not discovered at that time. Mendeleev gave space in periodic table for each of them and he named them as Eka- silicon respectively. Later they were discovered according to Mendeleev's prediction.

iii) Correction of doubtful atomic weight: Atomic weight of some elements was calculated incorrectly. Mendeleev helped to correct it with the help of the of the arrangement of elements in the periodic table.

Name some elements whose atomic weight was corrected by the arrangement of the elements in the Mendeleev's periodic table.

Gold (Au),platinum (Pt), Aluminium (AI) etc.

Write down the defect of Mendeleev's periodic table?

i) Anomalous position of hydrogen: Hydrogen is placed with alkali metals in group-I but it is non-metal and its property is similar to the halogens of group-VII.

ii) Anomalous pair of elements: Some elements having higher atomic weight precede the elements with lower atomic weight. For example Ar (Atomic weight 39.9) precedes K (Atomic weight 39.1). Similarly Co ( Atomic weight 58.9) precedes Ni (Atomic weight 58.7)

iii) Postion of istotope:If periodic table was made according to the increasing order of atomic weight then isotope should also have had position in the periodic table.

iv) Some dissimilar elements were placed together but some similar elements were placed in different group. For example CU,AG,AU etc. are placed in group I with alkali metals like Li, Na, k etc. But similar elements like Cu and Hg were placed in different group i.e.group I and II respectively.

v) Position of landthanides and actinides: There wasn't any place for landthanides and actinides.

vi) Position of elements of group VIII was not clear because nine elements of group VIII were placed in the form of triad without any justification.

Chemistry

How much of copper sulphate crystals will be seperated if 25g saturated solution of copper sulphate at 60^oC is cooled down to 30^oC if solubility of copper sulphate at 60^oC is 50 and at 30^oC is 30 respectively?

According to the statement:

At 60^oC, 50 g of CuS0₄ forms 150 g of saturated solution (50g solute+ 100g solvent)

At 30^oC, 30 g of CuS0₄ forms 130 g of saturated solution (30g solute+ 100g solvent)

The difference in the weight of solution is: 150 - 130 = 20g

Therefore, 150g of saturated solution when cooled from 60^oC to 30^oC separates 20g of CuS0₄

1g of saturated solution when cooled from 60^oC to 30^oC separates 20/150 g of CuS0₄

25g of saturated solution when cooled from 60^oC to 30^oC separates of (20/150)*25g CuS0₄ = 3.33g

Thus 3.33 g copper sulphate is separated by cooling the solution from 60^oC to 30^oC.

Heterogeneous mixture:

A mixture which can be seen through our naked eyes is called heterogeneous mixture. E.g. mixture of sand and rice or which can be separated by easily.
According to the particle size mixture can be divided into three types

Solution:

Homogeneous mixture of two or more substances is called solution. Example: Salt and water, alcohol and water, Air, brass etc. The substance which is dissolved is called solute and the substance that dissolves is called solvent. In the solution the diameter of the particle of a substance is smaller than 10^-5 cm. They are Invisible (Visible under ultra-microscope). They cannot be settle down and can't be filtered. They are transparent and Homogeneous.

Solution = solvent + solute

Colloids:

If the diameter of the particle of a substance in a solution ranges from 10^-5 cm to 10^-7 cm then the mixture is called colloidal. Particle size in colloidal solution is intermediate between solution and suspension. The particles of colloids cannot be seen by naked eye. They may be visible in beam of light, Do not settle down in ordinary condition, cannot be filtered, cloudy transulent and Intermediate of homogeneous and Heterogeneous.

Example: RNA, DNA in blood, particles of milk, Gum, Dust in air

Suspension:

It is the heterogeneous mixture of solid and liquid particles in which particle size is 10^-3 cm or bigger. They are visible in naked eye, settle down easily, can be filtered, apaque, They are Heterogeneous.

E.g. smoke particles in air, Sand water, Muddy water etc.

Saturated solution

The solution in which the solvent cannot dissolve the solute anymore, at the given temperature then it is known as saturated solution at that temperature.

The solution which cannot dissolve excess amount of solute in it at the given temperature is call unsaturated solution at that temperature.

When we dissolve solute in a solvent and there comes a time when the solute won't get dissolved anymore, then this solution is considered as saturated solution. On Heating it becomes unsaturated. It has more density. it has more concentration of solute, precipitation of the of the solute appears on cooling.

Example: When we pour sugar in the water and stir it, the sugar keeps dissolving but on further dissolving the sugar, a state will come when the sugar will not get dissolved in the water. At this point, the solution is a saturated solution.

Unsaturated solution

A solution at a state before saturation in called an unsaturated solution. In other words, the solution which can dissolve the solute at the given temperature is known as unsaturated solution at that temperature.

The solution which can dissolve excess amount of solute in it at the given temperature is call unsaturated solution at that temperature.

On Heating it remains unsaturated. It has less density. it has less concentration of solute, precipitation of the of the solute doesn't appears on cooling.

Solutions having low concentration of solute are called dilute solution.

Solutions having high concentration of solute are called concentrated solution.

Supersaturated solution:

The saturated solution at higher temperature that holds excessively more solute then the required amount for saturated solution at that temperature is called supersaturated solution.

When excess amount of solute particle is dissolve in a solution when heating is known as supersaturated solution.

Importance of Solution

- Oxygen is found dissolved in water and in air which is used by living organism for respiration.

- Plants take different minerals and salts from the soil in the form of a solution.

- The digested food particles reach the different parts of the body in the form of a solution.

- Most of the reaction taking place easily in the form of solution.

- Solution is more essential in many industries.

Solubility of the substance

The solubility of a substance (Solute) at a given temperature is defined as the amount of the substance(Solute) dissolved in 100g of solvent to make a saturated solution at that temperature.

The solubility of a substance at certain temperature can be given by

Solubility S = ( weight of solute in g/weight of solvent in g) * 100 [At constant Temperature]

Effect of the temperature on solubility

The relationship between increase in temperature and solubility is that the solubility is directly proportional to the increase in the temperature i.e. At high temperature the solubility of a solution is high so it is able to dissolve more solute, but when it is cooled, the solubility of the solution decreases and due to which the solute separate out as solid.

Solubility curve

Solubility curve is curve obtained by the plotting the solubility of the substance at different temperature against these temperatures.

Solubility Curve

From the solubility curve various information can be obtained which are listed below

I. Comparative study of the solubility of different solutes can be done.

II .The solubility of solute at any temperature can be found out.

III. The change in solubility on changes in temperature can be observed.

Crystal:

A crystal is a piece of solid particles which has a regular geometrical shape, smooth surfaces and sharp edges. They are solid particles with a definite or regular shape. They are pure substance with a fixed melting point.

Crystallization:

When the saturated mixture of a solid in a liquid at a high temperature is allowed to cool down, solid deposits in a certain geometrical shape called crystal .The process in which crystals are formed by cooling a hot saturated solution of solid materials is known as crystallization.

Amorphous solid:

Those solid substance which do not have any definite geometrical shapes are called Amorphous solid. On heating they don't melt but becomes less viscous. Lime, glass, rubber, plastic etc.

Crystalline Solids:

Crystalline Solids have typical geometrical shaped along with definite and rigid morphology. Eg; NaCl, Copper sulphate etc. are crystalline solid.

It is not only an observational Science but strongly effect the life of each and every living organism on the Earth. The origin of Earthquake is as old as the origin of the Earth, But due to lack of knowledge and scientific instruments it is tremendous challenge for ancient scientists and geophysicists to collect and analysis the Earthquake data. Now a day's science and technology grew up their maturities, collecting and analysis of Earthquake movement is an easy job \cite{1}.\\ \\ Cyclic variations of seismicity possibly provide insights into the physics of earthquake triggering. Seasonal variations have been in particular observed in various contexts and related to factors such as snow loading, precipitation and variations of the water table\cite{1}.\\ \pagenumbering{arabic} Seismic waves travelling through earth carry lot of information regarding valuables buried under the earth crust. These information are useful in many fields of seismology, geological engineering, mining engineering and oil and gases industries etc. Speed of waves depends upon the elastic properties of the medium. They provide us many characteristics i.e. homogeneity or heterogeneity, isotropy or anisotropy and discontinuity present in the medium. On the analysis of the velocities and travel times of P, SV, SH and surface waves, we can explore the possibility of buried beneath the earth crust\cite{2}.\\ \\ An earthquake (also known as a quake, tremor or temblor) is the shaking of the surface of the Earth, resulting from the sudden release of energy in the Earth's lithosphere that creates seismic waves. Quaking or shaking of the earth is a common phenomenon undoubtedly known to humans from earliest times. Prior to the development of strong-motion accelerometers that can measure peak ground speed and acceleration directly, the intensity of the earth-shaking was estimated on the basis of the observed effects, as categorized on various seismic intensity scales. Only in the last century has the source of such shaking been identified as ruptures in the earth's crust, with the intensity of shaking at any locality dependent not only on the local ground conditions, but also on the strength or magnitude of the rupture, and on its distance\cite{3}. \\ \\ The April 25 2015 earthquake in Nepal and the subsequent aftershocks resulted in losses not only in terms of lives and physical infrastructures but also of historical, social, cultural and economic aspects of the country and its population. Thirty-one out of the 75 districts of Nepal were affected by this devastation with 14 of them located in the Central and Western mountains and hills including Kathmandu Valley, and categorized by the Government of Nepal as the most affected. An estimated 5.4 million people live in these 14 districts. \\ \\ In an earthquake, the initial movement that causes seismic vibrations occurs when two sides of a fault suddenly slide past each other. A fault is a large fracture in rocks, across which the rocks have moved. Faults can be microscopic or hundreds-to-thousands of kilometers long and tens of kilometers deep. The width of the fault is usually much smaller, on the order of a few millimeters to meters. \subsection{Frequency and spatial distribution} The frequency magnitude distribution of earthquake between 01 January 2010 and 25 August 2019 can be studied.

The Gutenberg$-$Richter model obtained by least squares fit to the data . The results indicate that the slope parameter (b-value) is equal to 0.85. This slope is less than 1, which implies a higher rate of occurrence of larger earthquakes than would be implied by a b-value of 1. The estimated b-value is the same as that presented by Adhikari et al. (2015) based on data from 45 days after the mainshock(April 25 2015), but higher than 0.76 as reported by Parajuli (2009) using data between 1100 and 2002\cite{4}. \subsection{Earthquakes away from plate boundaries} Where plate boundaries occur within the continental lithosphere, deformation is spread out over a much larger area than the plate boundary itself. In the case of the San Andreas fault continental transform, many earthquakes occur away from the plate boundary and are related to strains developed within the broader zone of deformation caused by major irregularities in the fault trace (e.g., the "Big bend" region). The Northridge earthquake was associated with movement on a blind thrust within such a zone. Another example is the strongly oblique convergent plate boundary between the Arabian and Eurasian plates where it runs through the northwestern part of the Zagros Mountains. The deformation associated with this plate boundary is partitioned into nearly pure thrust sense movements perpendicular to the boundary over a wide zone to the southwest and nearly pure strike-slip motion along the Main Recent Fault close to the actual plate boundary itself. This is demonstrated by earthquake focal mechanisms\cite{5}. \\ \begin{figure}[h] \centering \includegraphics[scale=0.7] {fig1.png} \caption{Tectonic and paleoseismological background of the 2015 Gorkha earthquake. Thick dashed arrows indicate lateral extension of surface rupture of past great earthquakes\cite{8}.} \label{157} \end{figure} Historical seismicity associated with the Main Himalayan Thrust(MHT) is characterized by infrequent, large megathrust earthquakes that occasionally break the MHT up to its frontal expression along the Main Frontal Thrust (MFT) \cite{6}. Paleoseismology has provided evidence for earthquakes with magnitudes exceeding M8.5 associated with surface ruptures reaching the MFT. However, historical records suggest that large, blind earthquakes do also take place, such as the 1833 earthquake (M7.3 - 7.7) that occurred near Kathmandu\cite{7}. The significance of these blind earthquakes in releasing part of the interseismically accumulated strain is of paramount importance for quantifying slip deficit of the MHT and for assessing associated seismic hazard. \pagebreak \section{Literature Review} [Gao, S. S., P. G.et.al, 2000]Seismicity has been monitored since 1995 from 21 vertical-component, short-period stations, operated by the Department of Mines and Geology (Kathmandu, Nepal) in collaboration with the Laboratoire Detection Geophysique (France). For the analysis presented here [Gao, S. S., P. G.et.al, 2000] have selected the period from 1995 to 2000, during this time\cite{9}the network geometry has not changed, nor has any major earthquake occurred nearby. As reported in previous studies \cite{2}, a large fraction of the seismicity is clustered along a belt following the front of the Himalaya with focal mechanisms indicating thrusting perpendicular to the range. As shown from the modelling of geodetic strain measured from GPS, this seismicity is associated with interseismic stress accumulation around the downdip end of the locked portion of the Main Himalayan Thrust (MHT) fault\cite{2}. Other clusters of seismicity occur farther north and are related to normal events along NS grabens \cite{7}.\\ [Bollinger, L., et al. 2004] restrict our analysis to events located within the band of seismicity beneath the Greater Himalaya. A total of 10569 earthquake event occurred within this area with local magnitudes ranging from $M_L$ = 0 to 6.3. Seismic productivity in the five years investigated exhibits a strong seasonal variation with seismicity rates in winter nearly double those in summer\cite{10}. The magnitude-frequency distribution of events recorded either in summer or in winter. The number of events, N, with magnitude above a given value $M_{L}$ follows approximately the Gutenberg-Richter relationship: \begin{equation} {Log_{10}}N({M\geq{M_L}})=a- b{M_L} \end{equation} with a, b value of 0.81$\pm$ 0.04 \cite{11}. The relationship is obeyed for magnitudes above a completeness magnitude, Mc, which we define here as the magnitude above which the number of events in the catalog is 95 of the number of events anticipated by equation (1). When summertime and wintertime events are considered separately, Mc shows an annual variation between $\sim$ 1.6 in winter and $\sim$ 2.1 in summer. This variation suggests that the Mc basically reflects the detection capacity of the seismic network and is lower in the winter than in the summer due to a higher seismic noise level. The number of events in summer is lower than that in winter at all magnitudes above the detection threshold, up to $M_L$ = 4.0, but with lower statistical significance. In order to test the statistical significance of the observation, generated 10000 random catalogs with the same number of events and the same frequency-magnitude distribution as in the real catalog. [Chen C, Ho C, Correa C.et.al 2010] have then varied the cut-off magnitude and computed the ratio of events occurring in the winter to those occurring in the summer\cite{12}. [Chen C,Ho C 2010]Analyzed seismic data with the help of frequency time analysis technique using a fourth order Butterworth filter to separate different band-pass data\cite{13}. Machado and Lopes [6] have analyzed global seismic data covering the period from 1962 up to 2011.They characterized the events by their magnitude ,location and time. The events are divided into groups either by according to F-E seismic reasons of earth or using a rectangular grid based on latitude and longitude co-ordinates. They developed two mathematical tools namely G-R distributions and mutual information and clustering analysis.Explored the possibility of the techniques to analyze seismic data for development of cost free and easy to use\cite{14}.\\\\ The M 7.8 2015 April 25 Gorkha earthquake devastated the mountainous southern rim of the High Himalayan range in central Nepal [Adhikari.et.al 2015]. The main shock was followed by 553 earthquakes of local magnitude greater than 4.0 within the first 45 days. In this study, we present and qualify the bulletin of the permanent National Seismological Centre network to determine the spatio-temporal distribution of the aftershocks. The Gorkha sequence defines a $\sim$140-km-long ESE trending structure, parallel to the mountain range, abutting on the presumed extension of the rupture plane of the 1934 M 8.4 earthquake\cite{15}. \\ \\ Various aspects of the 2015 Gorkha Earthquake and its aftershocks are presented, and different hypotheses about the nature of long period pulses observed in ground motion record in Kathmandu Valley are critically discussed and reviewed. A comparison between the local magnitude of the earthquakes reported by NSC and moment (or body wave) magnitude reported by USGS showed some interesting results. For earthquakes with an Mw between 4 and 5.5, the local magnitude is found, on average, to be smaller than Mw. This is in contradiction to observations from other parts of the world where, for such small events, these have been found to be approximately the same\cite{16}. \subsection{Concept of an Earthquake} An 'Earthquake' is the tectonic movements to release built-up energy when two earth strata relativejy move in relation to each other along a fault. In geological structuring of the earth, various distinct layers are formed and have fractures (faults), relative inclinations. In certain portion of the earth crust there appears to be a continuous strain movement between earth strata. When the stresses developed by such strain exceed the strength of the earth crust materials, a slip occurs between the two portions of the crust and energy is released causing earthquake.\\ \\ The types of waves produced on account of the release of energy depend somewhat on the location of the origin (earthquake focus). From the focus waves radiate in all directions. At the epicentre (point lying on the earth surface vertically above the focus) the shaking is the most intense. Seismic waves are of three types; (i) P waves, (ii) S waves, and (iii) L or Surface waves. Surface waves are responsible for causing earthquakes and hence damages. \subsection{Objective} The Large number of earthquake data are arranged and study about their relations with time.my Objective of the research work are as follows : \begin{itemize} \item[i] Study the seismic data and relation of time with the Magnitude of the Earthquake. \item[ii] Study the magnitude and calculate difference between two event time in day and nature of graph. \item[iii] Calculate the b value of the cumulative Number(N) and plot the cumulative number with magnitude graph. \end{itemize} \pagebreak \section{Methodology} \subsection{Maximum And Minimum Magnitude} The maximum magnitude of earthquake for each demarcated source zone in the present study was determined based on both historical and instrumental earthquake as well as the largest earthquake that occurred in adjacent potential zones that have a similar geology and tectonic environment. The Himalaya of Nepal has experienced great earthquakes in 2015 ($M_w$ = 7.8). That great earthquake allowed us to determine the expected largest earthquake magnitudes in the Nepal$^{'}$s Himalayan section. In the data source the minimum magnitude and its location and date can be easily handled by using QBasic and Excel program. \subsection{Time change with Magnitude} To calculate the time change(interval between two events) was calculated by the difference between two date of events in days. After analysis of this data, we can easily show the time difference and magnitude. The time variation of the earthquake magnitudes at certain place of can be compared. \subsection{Analysis of seismic Data and It's Source} Excel and QBasic Program is used to analyse the large number of earthquake data. In this we Analyse the date, time, magnitude, latitude, longitude and epicentre were arranged in column by using QBasic program and calculate the change in date. Also calculated the change in time so that we can easily distinguish the earthquake magnitude at certain time change. We can see the time Variation of magnitude. An algorithm used for analysis of seismic data has two phases i.e. mapper phase and reducer phase. In the mapper phase, earthquake data and file-contents assumed as key and value pair. After that authors emitted the magnitude of earthquake having value greater than 8. In the Reducer phase, initialized output result as null value and assigned the values that contained magnitude of earthquake more than 8. Then entered magnitude as key and output as value pair which could show the final results. Researchers have been using computer simulations to better understanding the mechanism of seismic waves to build safer structures to minimize the damage occurred during earthquake. \\ \\ The earthquakes data is found in the seismic data source website (www.seismonepal.gov.np) there are many data ranges from date to date but in this study only data ranges from 2010 to 2019 was taken because the main shocks is happened at 2015 so we want to check the relation of magnitude before and after main shocks. These data can be easily found in the website and can be analysis by using computer programming QBasic and Excel. \pagebreak \subsection{Average annual occurrence rate and b value} The earthquake catalogue of Nepal for the period 2010$-$2019 suggests that the database before 2010 is inadequate to delineate earthquakes with less than surface wave magnitude 4.0. The database utilized here is more complete from 2010, when many earthquake records became available from modern seismic instruments. Earthquakes with a surface wave magnitude equal to or greater than 4.0 from 2010 to 2019 were used to estimate the average annual occurrence rate of earthquakes and b using the frequency magnitude relation (Gutenberg and Richter, 1944) \begin{equation} {Log} N =a- bM \end{equation} where N is the cumulative number of earthquakes with magnitude equal to or greater than the specified magnitude M, and a and b represent the Gutenberg and Richter (G-R) parameters for a particular region. In this study, the estimated b value is 0.85 for the entire region. The frequency magnitude distribution of earthquakes with surface wave magnitude equal to or greater than 4.0 \subsection{Calculation of difference in time with magnitude} Seismicity has been monitored since 1995 from 21 vertical-component, short-period stations, operated by the Department of Mines and Geology (Kathmandu, Nepal) in collaboration with the Laboratory de Detection et de Ge0$-$physique (France). For the analysis presented here we have selected the period from 2010 to 2019, during which time i subtract any two consecutive time and give the interval between the consecutive event of earthquake. To calculate the time change Microsoft Excel Program is used. The date range is set into a column and subtract consecutive date and add first data and second data also calculate the change in time and add to it. Finally date changes vs magnitude is obtained. \pagebreak \section{Result and Discussion} The earthquake of Nepal having larger magnitude $M_L$ = 7.6 and epicentre at gorkha and the magnitude which is less than 4.0 are of many socks after main socks. The Time Variations of the magnitude of 2010 AD to 2019 AD all the data are in one graph is given Below. In the Figure2 there is the variation of magnitude before and after main shock. \begin{figure}[h] \centering \includegraphics[scale=0.4] {1.png} \caption{Plot of magnitude Vs Date ranges from 2010AD to 2019AD} \label{157} \end{figure} \\ From above graph it can shown that before the main shock there are so less magnitude sock and main shock is happened and then so many compan of shock less than 4.0 and grater than 4.0 is observed. The Main shock is 7.6 at 2015$-$4$-$25 at 6:11am and other shock are happened after this shock. The Minimum magnitude is 4.0 and there are 141 data having different date and epicentre. For the easy studying we are separating Figure2 in different years. \pagebreak \begin{figure}[h] \centering \includegraphics[scale=0.4] {2019.png} \caption{Plot of Magnitude Vs Date 2019AD} \label{157} \end{figure} \\\\ In the above graph we can see that the Maximum Magnitude is 5.0 and Minimum Magnitude is 4.0, in this year at initially Magnitude is high and it becomes decreasing and then again increasing and decreasing continuously up to till now. After High magnitude shock then loosest magnitude shock is appears. The change in time between first two peak is 67days and second and third peak is 88 days.\\ \\ In the graph below, 2018 and 2019 whole year there is no any relationship between two years and every month. There is no any correlation between any month of the these two years. Above 6.5 magnitude shock is only one in the whole year of 2018. In the 2018 graph the time change between two peak magnitude is 134days.\pagebreak \begin{figure}[h] \centering \includegraphics[scale=0.6] {20181.png} \caption{Plot of Magnitude Vs Date of 2018 and 2017 and compare the graph.} \label{157} \end{figure} And also in 2017 there are two magnitude which is greater than 5.5 and other smaller components are appears. So there is no any correlation of magnitude and time.\\ But in 2016 and 2015 there is large number of smaller and larger components of earthquake was appeared. In the 2015 and 2016 data, when high component of earthquake was happened then large number of shocks are appears after time to time. In 2015 one component having largest magnitude 7.6 from 2010AD to till Now. \pagebreak \begin{figure}[h] \centering \includegraphics[scale=0.65] {20161.png} \caption{Plot of Magnitude Vs Date of 2016 and 2015 and compare the graph.} \label{157} \end{figure} \subsection{Frequency distribution} The frequency distribution of earthquake events between 01 January 2010 and 25 August 2019 is presented in Fig. 5. The Gutenberg$-$Richter model obtained by least squares fit to the data is shown in the figure. The results indicate that the slope parameter (b-value) is equal to 0.85. This slope is less than 1, which implies a higher rate of occurrence of larger earthquakes than would be implied by a b-value of 1. The estimated b-value is the same as that presented by Adhikari et al. (2015) based on data from 45 days after the mainshock, but higher than 0.76 as reported by Parajuli (2009) using data between 1100 and 2002. \begin{center} \large\bf {Calculation of value of b} \end{center} We know that from the equation, \begin{equation} {Log} N =a- bM \end{equation} \begin{equation} \sum {Log} N =na- b\sum M \end{equation} \begin{equation} \sum (M \times {Log} N) =a\sum M- b\sum (M)^2 \end{equation} On Solving equation (4) and (5) we get the value of b which is equal to 0.84. Which is calculated by the help of table Below \begin{table}[h] \tiny \caption[]{Cumulative Number and Magnitude Table} $$ \begin{array}{p{0.3\linewidth}ccccc} \hline \hline \noalign{\smallskip} Magnitude &{\rm Number \,of \, Earthquake}&{\rm Log N}&{\rm M\times LogN}&{\rm Magnitude^2}\\ (ML) &(N)&&&&\\ \noalign{\smallskip} \hline \hline \noalign{\smallskip} 4 & 140 & 2.146128036 & 8.584512143 & 4.605865546 \\\\ 4.1 & 103 & 2.012837225 & 8.252632621 & 4.051513693 \\\\ 4.2 & 115 & 2.06069784 & 8.654930929 & 4.246475589 \\\\ 4.3 & 62 & 1.792391689 & 7.707284265 & 3.212667969 \\\\ 4.4 & 58 & 1.763427994 & 7.759083172 & 3.109678288 \\\\ 4.5 & 61 & 1.785329835 & 8.033984258 & 3.18740262 \\\\ 4.6 & 37 & 1.568201724 & 7.213727931 & 2.459256647 \\\\ 4.7 & 25 & 1.397940009 & 6.570318041 & 1.954236268 \\\\ 4.8 & 24 & 1.380211242 & 6.62501396 & 1.904983072 \\\\ 4.9 & 13 & 1.113943352 & 5.458322426 & 1.240869792 \\\\ 5 & 23 & 1.361727836 & 6.80863918 & 1.854302699 \\\\ 5.1 & 12 & 1.079181246 & 5.503824355 & 1.164632162 \\\\ 5.2 & 11 & 1.041392685 & 5.415241963 & 1.084498725 \\\\ 5.3 & 9 & 0.954242509 & 5.0574853 & 0.910578767 \\\\ 5.4 & 3 & 0.477121255 & 2.576454775 & 0.227644692 \\\\ 5.5 & 12 & 1.079181246 & 5.935496853 & 1.164632162 \\\\ 5.6 & 4 & 0.602059991 & 3.371535951 & 0.362476233 \\\\ 5.7 & 4 & 0.602059991 & 3.431741951 & 0.362476233 \\\\ 5.8 & 1 & 0 & 0 & 0 \\\\ 5.9 & 3 & 0.477121255 & 2.815015403 & 0.227644692 \\\\ 6 & 1 & 0 & 0 & 0 \\\\ 6.2 & 1 & 0 & 0 & 0 \\\\ 6.6 & 1 & 0 & 0 & 0 \\\\ 6.8 & 2 & 0.301029996 & 2.047003971 & 0.090619058 \\\\ 6.9 & 1 & 0 & 0 & 0 \\\\ 7.6 & 1 & 0 & 0 & 0 \\\\ $\sum$ M = & \sum N = & \sum {Log} N= & \sum (M \times {Log} N)= &\sum (M)^{2}=\\\\ 139.1 & 727 & 24.99622696 & 117.8222494 & 37.42245491 \\\\ \noalign{\smallskip} \hline \end{array} $$ \end{table} \begin{figure}[h!] \centering \includegraphics[scale=0.45] {logn.png} \caption{Frequency Magnitude distribution of earthquakes betweens 01 January 2010 and 25 August 2019.

The change in time is expressed in days and it is calculated from the subtraction of two events. From the graph we can say found that the gap between any two shock with their respective magnitude. Many methods have been developed for predicting the time and place in which earthquakes will occur. Despite considerable research efforts by seismologist, scientifically reproducible predictions cannot yet be made to a specific day or month. However, for well $-$ understood faults the probability that a segment may rupture during the next few decades can be estimated. Earthquake warning system have been developed. \\ \\ The graph show the magnitude and change in time of any two events expressed in days is shown in figure 7. In the low time difference there is low magnitude shock is appears. After the large time difference, when large magnitude of earthquake is happened then large number of smaller components are appears in short duration of time. After the main shock the energy is stored and after long time again large shock should happened but the date of 2015 main shock many more smaller shock less than main shocks are appeared. To become study easier we are separating figure 7 into different part. \begin{figure}[h] \centering \includegraphics[scale=0.4] {tmc.png} \caption{The graph of interval of any two constitutive event of earthquake from 2010AD to 2019AD} \label{157} \end{figure} \pagebreak From the separate parts of all graph in Figure 8, the maximum magnitude is 6.5 and there are many minimum magnitude of earthquake is appeared. In this first graph when time change is minimum then magnitude is also minimum when some of the component is maximum magnitude and before and after maximum shock more minimum shocks are appears. \begin{figure}[h!] \centering \includegraphics[scale=0.8] {tchvsmag1.png} \caption{The graph of interval of any two constitutive event of earthquake} \label{157} \end{figure} In the second graph there is the main shock which has magnitude of 7.6 and many more minimum shock are appears. In the third graph there are many more minimum magnitude of earthquake is appeared there is the another maximum value of magnitude of earthquake betweens 1940 and 1945 days time difference. After than increasing and decreasing curve is obtained. In the 4$^{th}$ graph one shock having magnitude 6.9 is appeared in betweens 3200 to 3300 days time difference and before this short magnitude shock of quake is happened and after this other smaller shocks of earthquake are appeared in this graph so that from all of the graph there is no any correlation between time difference and magnitude is obtained Which is shown in graph Below. \begin{figure}[h!] \centering \includegraphics[scale=0.8] {tchvsmag2.png} \caption{The graph of interval of any two constitutive event of earthquake} \label{157} \end{figure} \section{Conclusion} From this study it is concluded that the there is no any correlation between any two event time with Magnitude. It means that when high shock earthquake was appeared in one day then after certain time chances of occurrence of another high or low shock can not be estimate. So there is no any relation between two event with their magnitude. But for the main shock then after it there may be large number of smaller shock of earthquake happen. Also from this study we plot the time change with their respective magnitude, and it is concluded that there is no any relation of time with the Magnitude of Earthquake. In this study the calculated value of b from the data is 0.84 and from Gutenberg-Richter relationship some other researcher was calculated the same value. In the graph cumulative number of N and with magnitude is found to be Straight line. \pagebreak \begin{table}[h] \tiny \caption[]{Earth Quake data from 2010-2019} $$
