NCERT CLASS 8 SCIENCE CHAPTER 4 COMBUSTION AND FLAME

Question 1.

List conditions under which combustion can take place.

Answer:

Combustion can take place when:

(a) there is a combustible substance.

(b) there is oxygen, which supports combustion.

Question 2.

Fill in the blanks.

(a) Burning of wood and coal causes _____ of air.

(b) A liquid fuel used in homes is ______.

(d) Fire produced by oil cannot be controlled by ______.

Answer:

(a) pollution

(b) LPG (liquefied petroleum gas)

(d) water

Question 3.

Explain how the use of CNG in automobiles has reduced pollution in our cities.

Answer:

The use of CNG (compressed natural gas) in automobiles has reduced pollution in our cities due to the following reasons:

(a) CNG emits fewer harmful gases like carbon dioxide, carbon monoxide, sulphur dioxide, and nitrogen dioxide, which contribute to global warming and acid rain.

(b) CNG combustion leaves behind no residue or particulate matter after burning, reducing air pollution.

Question 4.

Compare LPG and wood as fuels.

Answer:

LPG:

Does not cause pollution on combustion.

Does not produce smoke.

It is a liquid fuel.

Has higher calorific value (55000 kJ/kg).

Can be easily transported, stored in cylinders.

Wood:

Pollutes air on combustion.

Produces smoke.

It is a solid fuel.

Has lower calorific value (17000 kJ/kg).

Not easily transported like LPG fuels.

Question 5.

Give reasons.

(a) Water is not used to control fires involving electrical equipment.

(b) LPG is a better domestic fuel than wood.

Answer:

(a) Water is not used to control fires involving electrical equipment because water is a good conductor of electricity and could result in electric shocks to the person trying to extinguish the fire.

(b) LPG is a better domestic fuel than wood because it produces no gases or smoke on combustion, leaves no residue, and has a higher calorific value compared to wood.

(c) Paper by itself catches fire easily because it has a low ignition temperature. However, when a piece of paper is wrapped around an aluminum pipe, the heat generated gets absorbed by the aluminum pipe, preventing the paper from reaching its ignition temperature and catching fire easily.

Question 7.

Name the unit in which the calorific value of a fuel is expressed.

Answer:

The calorific value of a fuel is expressed in kilojoules per kilogram (kJ/kg).

Question 8.

Explain how CO2 is able to control fires.

Answer:

CO2 (carbon dioxide) is able to control fires through the following mechanisms:

CO2 is heavier than oxygen and forms a blanket around the fire, depriving it of oxygen and suppressing the flames.

By displacing oxygen, CO2 reduces the concentration of oxygen required for combustion.

CO2 absorbs heat and lowers the temperature of the burning material, further aiding in fire control.

Question 9.

It is difficult to burn a heap of green leaves, but dry leaves catch fire easily. Explain.

Answer:

Green leaves contain moisture, which increases their ignition temperature, making it difficult to burn them. On the other hand, dry leaves have no moisture content, resulting in a lower ignition temperature. Therefore, dry leaves catch fire easily as they reach their ignition temperature more quickly compared to green leaves.

Question 10.

Which zone of a flame does a goldsmith use for melting gold and silver, and why?

Answer:

A goldsmith uses the outermost zone of a flame, known as the non-luminous zone, to melt gold and silver. This zone is the hottest part of the flame, with the highest temperature. By utilizing the non-luminous zone, the goldsmith can achieve the high temperatures necessary for melting gold and silver efficiently.

Question 11.

In an experiment, 4.5 kg of a fuel was completely burnt. The heat produced was measured to be 180,000 kJ. Calculate the calorific value of the fuel.

Answer:

Calorific value of a fuel = Heat produced / Amount of fuel

Calorific value = 180,000 kJ / 4.5 kg

= 40,000 kJ/kg

Question 12.

Can the process of rusting be called combustion? Discuss.

Answer:

The process of rusting is not considered combustion. Combustion is a rapid chemical reaction that occurs between a fuel and oxygen, resulting in the release of heat and light. Rusting, on the other hand, is a slow oxidation process that occurs when iron or steel reacts with oxygen and moisture in the presence of air. While rusting does release some heat during the formation of iron oxide, it is a gradual process that does not involve the rapid release of energy and light characteristic of combustion.

Question 13.

Abida and Ramesh were doing an experiment in which water was to be heated in a beaker. Abida kept the beaker near the wick in the yellow part of the candle flame. Ramesh kept the beaker in the outermost part of the flame. Whose water will get heated in a shorter time?

Answer:

Ramesh's water will get heated in a shorter time because he placed the beaker in the outermost part of the flame, which is the hottest zone. The outermost part of the flame has the highest temperature, while the yellow part of the flame, where Abida placed the beaker, has a lower temperature. Therefore, Ramesh's water will receive more heat energy and heat up faster compared to Abida's water.

(a) False: Fossil fuels cannot be made in the laboratory.

(b) False: CNG is not more polluting than petrol.

(d) True: Coal tar is a mixture of various substances.

(e) False: Kerosene is a fossil fuel.

Explain why fossil fuels are exhaustible natural resources.

Fossil fuels are exhaustible natural resources because they take millions of years to form, and we are using them much faster than they can be replenished. Once we use up all the fossil fuels, we cannot make more in a short time.

Describe the characteristics and uses of coke.

Coke is a black and porous substance made from coal. It is mostly made of carbon.
Coke is used as a fuel because it burns well and produces a lot of heat.
It is also used in industrial processes, especially in making iron and steel.

Explain the process of the formation of petroleum.

Petroleum is formed from the remains of plants and animals that lived in the sea millions of years ago.
Over time, these remains were buried under layers of sediment.
The pressure and heat from the layers of sediment turned the remains into petroleum, which is a thick, dark liquid.

They can also cause environmental damage by polluting water bodies and soil.

9. What are antibiotics? What precautions must be taken while taking antibiotics?

Ans: Antibiotics are medicines that are used to treat bacterial infections. They work by killing or inhibiting the growth of bacteria. Some precautions that must be taken while taking antibiotics are:

Antibiotics should only be taken when prescribed by a doctor.

The entire course of antibiotics should be completed, even if the symptoms of the infection have disappeared.

Antibiotics should not be taken unnecessarily, as this can lead to the development of antibiotic-resistant bacteria.

Alcohol should be avoided while taking antibiotics as it can reduce their effectiveness.

CLASS 8 SCIENCE Ch 1: CROP PRODUCTION AND MANAGEMENT

2023-04-23T12:37:00.004+05:30

CLASS 8 SCIENCE Ch 1: CROP PRODUCTION AND MANAGEMENT

Ans: 1.

(a) The same kind of plants grown and cultivated on a large scale at a place is called a crop.

(b) The first step before growing crops is preparation of the soil.

(d) For growing a crop, sufficient sunlight and nutrients and water from the soil are essential.

Ans: 3

(a) Examples of Kharif crops are paddy and maize.

(b) Examples of Rabi crops are wheat and mustard.

Ans: 4

(a) Preparation of soil: Preparation of soil refers to the process of loosening and turning the soil to make it suitable for the growth of crops. This involves ploughing, levelling, and adding manure or fertilisers to the soil.

(b) Sowing: Sowing is the process of planting seeds in the soil for growing crops. This is done either manually or using machines like seed drills.

(c) Weeding: Weeding involves removing unwanted plants, i.e., weeds, from the crop field. This is done manually or using tools like a hoe.

(d) Threshing: Threshing is the process of separating grains from the harvested crop. This is done by beating the crop or using machines like a thresher.

Ans: 5

Fertilisers are different from manure in that fertilisers are chemical substances that are artificially made to provide nutrients to the soil and enhance plant growth. They are available in concentrated forms and are easy to apply. On the other hand, manure is organic matter that is obtained from decomposed animal waste, crop residue, or compost. It is an excellent source of nutrients and helps to improve soil fertility.

Ans: 6

Irrigation refers to the process of supplying water to crops to support their growth. Two methods of irrigation that conserve water are drip irrigation and sprinkler irrigation. In drip irrigation, water is slowly dripped directly to the plant roots, thereby reducing water loss due to evaporation or runoff. In sprinkler irrigation, water is sprayed in a controlled manner over the crop field, which also helps to reduce water loss.

Ans: 7

Wheat is a Rabi crop, which means it is typically grown during the winter season. If it is sown in the kharif season, it will not be able to grow properly as it requires cool temperatures and low humidity for proper growth. Additionally, the monsoon rains during the kharif season can lead to waterlogging and damage to the wheat crop.

Ans: 8

Continuous plantation of crops in a field can lead to soil depletion, erosion, and loss of nutrients. This is because crops absorb nutrients from the soil, and if the same crop is grown repeatedly, the soil becomes depleted of those nutrients. This can be prevented by practising crop rotation, where different crops are grown in the same field in different seasons, or by adding manure or fertilisers to the soil.

Ans: 9

Weeds are unwanted plants that grow in the crop field and compete with the crop for resources like water and nutrients. They can be controlled by using manual methods like hand weeding or using tools like a hoe. Weeds are also controlled by using certain chemicals, called weedicides

Do you think the victims of the Bhopal gas tragedy received justice?

The victims of the Bhopal gas tragedy may not have received complete justice as many were not adequately compensated for their losses and sufferings. The legal proceedings and settlements took a long time, and some responsible parties were not held accountable. The tragedy also highlighted the need for stronger laws and regulations to prevent such incidents from happening in the future.

What do we mean by law enforcement, who is responsible for enforcement, and why is it important?

Law enforcement refers to the process of enforcing laws and regulations to ensure compliance and maintain social order. The responsibility for enforcement lies with various authorities such as the police, courts, and other government agencies. Enforcement is crucial to ensure that laws are obeyed, rights are protected, and justice is served. Without enforcement, laws are meaningless, and individuals or groups may violate them without any consequences.

How can laws ensure fair markets? Give two examples.

Laws can ensure fair markets by:

Regulating competition to prevent monopolies and unfair business practices
Protecting consumers from fraud and exploitation through laws such as consumer protection laws

How would your life change if you were a worker in a chemical factory that had to move 100 km away due to government orders?

As an AI language model, I cannot imagine or feel emotions like a human being. However, if a chemical factory had to move 100 km away, workers' lives would be significantly affected. They may have to relocate, find new housing and schools, and face a disrupted work-life balance. They may also face uncertainties regarding job security, income, and benefits.

What are the various roles of the government related to law and social justice?

The various roles of the government related to law and social justice include:

Making laws and regulations to promote justice and protect citizens' rights
Enforcing laws and regulations through various agencies and authorities
Providing legal aid and support to those who cannot afford it
Promoting awareness about legal rights and procedures
Providing social welfare schemes and programs for marginalized and disadvantaged sections of society
Ensuring accountability and transparency in governance and administration

What are the sources of environmental pollution in your area? What steps are being taken to reduce pollution, and can you suggest other measures?

Sources of environmental pollution may include industries, vehicles, waste disposal, and construction activities. Steps being taken to reduce pollution may include the use of clean technologies, promoting public transportation, waste management and recycling, and enforcing pollution control laws. Other measures could include promoting renewable energy sources, creating green spaces, and promoting sustainable practices.

How was environment treated earlier? What has been the change in perception? Discuss.

In the past, the environment was treated with little regard for its importance or protection. People believed that natural resources were unlimited and could be exploited without consequence. As industrialization increased, pollution and deforestation became widespread problems that led to health issues and ecological damage. However, over time, there has been a growing awareness of the need to protect the environment. This change in perception has led to the creation of laws and regulations to prevent pollution, protect wildlife, and conserve natural resources. People have also become more aware of their personal impact on the environment and have started taking steps to reduce their carbon footprint.

What do you think the famous cartoonist R.K.Laxman is trying to convey in this cartoon? How does it relate to the 2016 law that you read about on page 123?

The cartoon by R.K. Laxman depicts a judge sitting on a bench with a massive pile of files in front of him. The files represent the backlog of cases in the Indian judicial system. The judge is portrayed as helpless and overwhelmed by the volume of cases. The cartoon highlights the issue of delayed justice in India and the need for judicial reforms to speed up the legal process.

This cartoon relates to the 2016 law on page 123, which aimed to address the issue of delays in the Indian legal system. The law proposed several measures to reduce delays, such as establishing special courts, using technology to expedite cases, and increasing the number of judges. The cartoon emphasizes the urgency of addressing the issue of delayed justice and the need for continued efforts to improve the efficiency of the legal system.

Ncert class 8 civics Chapter 9: PUBLIC FACILITIES

Why do you think there are so few cases of private water supply in the world?

Private water supply is not common because water is considered a basic human need and a public good.
Governments generally take the responsibility of providing water to their citizens.
Privatizing water supply can lead to issues of access, affordability, and quality control.

Do you think water in Chennai is available to and affordable by all? Discuss.

The availability and affordability of water in Chennai are not equal for all.
Some areas experience water scarcity and have to rely on private water tankers for supply, which can be expensive.
Low-income households may have difficulty affording water bills or paying for private water sources.

How is the sale of water by farmers to water dealers in Chennai affecting the local people? Do you think local people can object to such exploitation of ground water? Can the government do anything in this regard?

The sale of water by farmers to water dealers in Chennai can lead to groundwater depletion, which can impact local people's access to water.
Local people can object to this exploitation and advocate for sustainable water management practices.
The government can regulate the sale of water and promote water conservation efforts.

Why are most of the private hospitals and private schools located in major cities and not in towns or rural areas?

Major cities have a larger population and a higher demand for private healthcare and education services.
Private hospitals and schools require a significant investment of resources, and investors tend to locate them in areas where they are likely to generate high returns on their investment.
There may be a lack of infrastructure and facilities in towns and rural areas, making it difficult to establish and maintain private hospitals and schools.

Do you think the distribution of public facilities in our country is adequate and fair? Give an example of your own to explain.

The distribution of public facilities in our country is not always adequate and fair.
For example, rural areas often have limited access to healthcare, education, and other public facilities, while urban areas tend to have better access.
The distribution of public facilities is often influenced by factors such as population density, economic development, and political power, which can lead to disparities in access and quality of services.

Take some of the public facilities in your area, such as water, electricity, roads and public transport. Is there scope to improve these? What in your opinion should be done? Complete the table.

Public Facility	Scope for Improvement	Suggested Actions
Water	Yes	1. Improve water supply infrastructure 2. Promote rainwater harvesting 3. Encourage water conservation practices
Electricity	Yes	1. Upgrade power generation and distribution systems 2. Promote renewable energy sources 3. Reduce power wastage
Roads	Yes	1. Repair and maintain existing roads 2. Build new roads where necessary 3. Promote public transportation and carpooling
Public transport	Yes	1. Increase number of buses and trains 2. Improve frequency and punctuality 3. Promote use of public transportation through awareness campaigns

Are the public facilities such as water, electricity, roads and public transport shared equally by all the people in your area? Elaborate.

No, the public facilities such as water, electricity, roads and public transport are not shared equally by all people in the area. There are several factors that contribute to this inequality, such as economic status, geographic location, and social status. For example, people living in rural areas may have less access to reliable electricity and public transportation than people living in urban areas. Similarly, people with higher income may have better access to water and roads than those with lower income. This inequality in access to public facilities needs to be addressed through policies and initiatives that promote equitable distribution.

Data on some of the public facilities are collected as part of the Census. Discuss with your teacher when and how the Census is conducted.

The Census is a nationwide survey conducted every 10 years in India. It is conducted by the Office of the Registrar General and Census Commissioner, India, under the Ministry of Home Affairs. The Census collects demographic and socioeconomic data about the population, including information about public facilities such as water, electricity, roads and public transport. The Census is conducted through a door-to-door survey where trained enumerators visit each household to collect the required information. The data collected from the Census is used by the government to plan and implement policies related to public facilities, among other things.

9. What is the trend in the establishment of private educational institutions in the country?

Private educational institutions such as schools, colleges, universities, technical and vocational training institutes are increasing rapidly in our country.

In contrast, government-run educational institutes are losing their significance.

This trend may have several impacts on education in the country. Some potential impacts include:

Access to education: Private educational institutions often charge higher fees compared to government-run institutions, making education less accessible to those from lower-income backgrounds.
Quality of education: Private institutions may focus more on profit-making and may not prioritize the quality of education as much as government-run institutions. However, some private institutions may offer higher-quality education due to better resources and infrastructure.
Equality in education: The growth of private institutions may exacerbate existing inequalities in education, as those who can afford to pay for private education may have an advantage over those who cannot.
Role of government: With the decline in the importance of government-run educational institutes, the role of the government in education may be reduced, potentially leading to a shift in priorities and resources.

Overall, the impact of the trend towards private educational institutions will depend on several factors, including the quality of education offered, the accessibility of education for all, and the role of the government in education.

Ncert class 8 civics Chapter 8: Confronting Marginalisation

What are two Fundamental Rights in the Constitution that Dalits can use to demand equality and dignity?

Article 17 of the Indian Constitution, which abolishes untouchability and forbids its practice in any form.
Article 15(1) of the Indian Constitution, which prohibits discrimination on the grounds of religion, race, caste, sex or place of birth.

Why did Rathnam use the 1989 Scheduled Castes and Scheduled Tribes (Prevention of Atrocities) Act to file a complaint?

Rathnam used the 1989 Scheduled Castes and Scheduled Tribes (Prevention of Atrocities) Act to file a complaint because he had faced discrimination and harassment due to his caste as a Dalit. The Act provides protection and legal recourse for Dalits and other marginalized communities against atrocities and discrimination.

Why do Adivasi activists, including C.K. Janu, believe that Adivasis can use the 1989 Act to fight against dispossession? Is there anything specific in the provisions of the Act that allows her to believe this?

Adivasi activists, including C.K. Janu, believe that Adivasis can use the 1989 Act to fight against dispossession because the Act provides protection to Scheduled Castes and Scheduled Tribes against atrocities, which includes dispossession of their land and resources. The Act recognizes the special vulnerabilities faced by these communities and provides legal recourse for them.

Ncert class 8 Civics Chapter 7: Understanding Marginalisation

2023-03-23T13:12:00.000+05:30

Ncert class 8 Civics Chapter 7: Understanding Marginalisation

What is marginalisation?

Marginalisation refers to the process of pushing a particular group or community to the margins of society, denying them access to resources, opportunities, and rights that are available to the rest of the society. It often results in social exclusion, discrimination, and deprivation of basic necessities of life.

Why are Adivasis becoming increasingly marginalised?

Adivasis are becoming increasingly marginalised due to various reasons such as the loss of their land and resources to industrialization, urbanization, and development projects, discrimination based on their cultural and social practices, and their lack of political representation and participation.

Why are the Constitution’s safeguards to protect minority communities important?

The Constitution’s safeguards to protect minority communities are important because they ensure that the rights of minority communities are protected and that they are not subjected to discrimination or marginalisation by the majority community. These safeguards also provide them with a platform to voice their concerns and to participate in the democratic process of the country.

What do you understand by the term minority?

Minority refers to a group of people who are numerically less in number as compared to the rest of the population and are often marginalized or discriminated against based on their religion, language, ethnicity, or culture.

List two reasons why Muslims are a marginalised community.

Two reasons why Muslims are a marginalised community in India are:

They are often subjected to discrimination and prejudice based on their religious identity, leading to their exclusion from mainstream society.
They face economic deprivation, with a significant proportion of the community living below the poverty line.

What are three things that you would tell your friend about the lives of Adivasis in India?

Adivasis have their own distinct cultures, traditions, and ways of life that are often threatened by the dominant culture of the mainstream society.
They have been historically deprived of their land and resources, leading to their marginalisation and poverty.
Adivasis face discrimination and prejudice based on their cultural practices and are often excluded from the benefits of development and welfare schemes.

Can you develop a short story on Adivasis to help Helen make her movie?

Once upon a time, in a small Adivasi village, there lived a young girl named Meena. She was known for her extraordinary skills in weaving beautiful baskets and mats using natural fibers. Despite her talent, Meena's family struggled to make ends meet and could not afford to send her to school. However, one day, a group of volunteers came to the village and started a community-based enterprise to promote local handicrafts. Meena joined the group and was able to showcase her skills to the world. Her hard work paid off, and she was able to earn a decent livelihood for her family. This success story of Meena and her community showcases the resilience and creativity of Adivasis despite the challenges they face in their daily lives.

Why are economic marginalisation and social marginalisation interlinked?

Economic marginalisation and social marginalisation are interlinked because economic deprivation often leads to social exclusion, and vice versa. For instance, if a particular group or community is economically disadvantaged, they may not have access to education, healthcare, or other basic necessities of life, leading to their social exclusion. On the other hand, if a community is socially excluded, they may not have access to employment or other economic opportunities, leading to their economic marginalisation. Therefore, economic and social marginalisation are closely linked and often reinforce each other.

NCERT CLASS 8 CIVICS CHAPTER 5 JUDICIARY

Why do you think an independent judiciary is necessary to carry out the important function of upholding the law and enforcing fundamental rights?
How does the Right to Constitutional Remedies connect to the idea of judicial review?
Fill in each tier with the judgments given by the various courts in the Sudha Goel case.
Tick the true sentences and correct the false ones based on the Sudha Goel case.
Why is the introduction of Public Interest Litigation (PIL) in the 1980s a significant step in ensuring access to justice for all?
In your own words, what did the judges mean when they said that the Right to Livelihood was part of the Right to Life, based on the Olga Tellis vs Bombay Municipal Corporation case?
Write a story around the theme, "Justice delayed is justice denied".

Answer:

An independent judiciary is necessary to carry out the important function of upholding the law and enforcing fundamental rights because it ensures that the judiciary is free from interference or influence from other branches of the government or powerful individuals or groups. This independence allows the judiciary to make impartial and fair judgments based on the law and the Constitution, without any fear or favor.
The Right to Constitutional Remedies connects to the idea of judicial review because it provides citizens with the power to approach the courts if they feel that their fundamental rights have been violated. Judicial review is the power of the courts to review the constitutionality of laws and executive actions, and the Right to Constitutional Remedies allows citizens to challenge such laws and actions if they believe that they are unconstitutional or violate their fundamental rights.
Supreme Court - upheld the decision of the High Court; High Court - convicted the accused of culpable homicide not amounting to murder and sentenced them to imprisonment; Lower Court - acquitted the accused of all charges.
(a) True; (b) False; (c) False (the decision of the Supreme Court is final and binding).
The introduction of Public Interest Litigation (PIL) in the 1980s is a significant step in ensuring access to justice for all because it allows individuals or groups to file lawsuits on behalf of those who are unable to approach the courts themselves, particularly marginalized and disadvantaged groups. PILs have been used to challenge unconstitutional laws, executive actions, and violations of fundamental rights, and have helped to bring about social and legal change.

6. 6. In the Olga Tellis vs Bombay Municipal Corporation case, the judges stated that the Right to Livelihood was a part of the Right to Life. This means that the Constitution of India recognizes that every person has a fundamental right to earn a livelihood and provide for themselves and their families. The right to life includes the right to livelihood, and denying a person the opportunity to earn a living is a violation of their fundamental rights. The judges recognized that homelessness and poverty are a serious threat to a person's right to life, and that the state has an obligation to ensure that every citizen has access to basic necessities and the means to earn a living.

2. 7. Radha had been fighting for justice for the past ten years. Her husband had been killed in a hit and run accident, and the driver had fled the scene. The police had promised her that they would find the culprit and bring him to justice, but as the years went by, Radha lost hope. She watched as the case was transferred from one court to another, and each time, a new judge would take over the case and ask for more evidence.

Radha was determined not to give up, even though it seemed that justice would never be served. She went from lawyer to lawyer, hoping that someone would take up her case and fight for her rights. But each time, she was turned away. No one wanted to take on a case that had been delayed for so long.

Finally, after ten long years, Radha's case was heard by a new judge. The evidence was presented once again, and this time, the judge took note of the fact that justice had been delayed for far too long. The driver was finally brought to court, and he confessed to the crime.

Radha felt a sense of relief wash over her as the judge pronounced the verdict. Justice had been served, but it had come at a great cost. Radha had lost ten years of her life fighting for what should have been a simple case. She realized that justice delayed is truly justice denied, and that the legal system needs to be more efficient in delivering justice to those who have been wronged

NCERT CLASS 8 CIVICS CHAPTER 4 UNDERSTANDING LAWS

2023-03-22T07:52:00.002+05:30

NCERT CLASS 8 CIVICS CHAPTER 4 UNDERSTANDING LAWS

Question: What is the 'rule of law' and give an example of a violation of it?

Answer: The 'rule of law' refers to the principle that all individuals and institutions are subject to and accountable to the law. It means that no one is above the law and that the law should be applied equally to all. A violation of the rule of law could be when a government official or politician engages in corrupt practices, such as accepting bribes or using their power for personal gain, without facing legal consequences.

Question: What are two reasons why historians refute the claim that the British introduced the rule of law in India?

Answer: Historians refute the claim that the British introduced the rule of law in India for two main reasons. Firstly, India had a long history of legal and judicial systems, including the system of dharma, which was based on religious and ethical principles.

NCERT CLASS 8 CIVICS Chapter 2: Understanding Secularism

List the different types of religious practice that you find in your neighbourhood. This could be different forms of prayer, worship of different gods, sacred sites, different kinds of religious music and singing etc. Does this indicate freedom of religious practice?

Different types of religious practices in my neighbourhood include:

Prayer and worship of different gods and goddesses, such as in temples, churches, and mosques.
Celebrations of religious festivals and holidays, such as Diwali, Eid, Christmas, and Easter.
Observance of religious customs and rituals, such as fasting and offering food and flowers to deities.
Religious music and singing, such as bhajans, hymns, and qawwalis.

This indicates freedom of religious practice as individuals and communities are able to practice their religion freely without interference or persecution.

Will the government intervene if some religious group says that their religion allows them to practise infanticide? Give reasons for your answer.

The government will definitely intervene if a religious group says that their religion allows them to practice infanticide. This is because the practice goes against the fundamental principles of human rights and violates the law of the land.

Complete the following table:

Objective	Why is this important?	Example of a violation of this objective
One religious community does not dominate another.	This is important to ensure equality and prevent discrimination against minority religious communities.	When members of one religious community prevent members of another religious community from practicing their religion freely.
The State does not enforce any particular religion nor take away the religious freedom of individuals.	This is important to maintain a secular and democratic society where individuals have the freedom to practice their religion without fear of persecution.	When the government favors one religion over another or restricts the religious practices of individuals or communities.
That some members do not dominate other members of the same religious community.	This is important to ensure equality and prevent discrimination within religious communities.	When members of a particular gender or caste are prevented from participating in religious practices or rituals.

Look up the annual calendar of holidays of your school. How many of them pertain to different religions? What does this indicate?

The annual calendar of holidays in my school includes holidays pertaining to different religions, such as Diwali, Christmas, Eid, and Guru Nanak Jayanti. This indicates that the school recognizes the diversity of its students and respects their religious beliefs and practices.

Find out some examples of different views within the same religion.

Examples of different views within the same religion include:

In Hinduism, there are different beliefs and practices among different sects, such as Vaishnavism, Shaivism, and Shaktism.
In Christianity, there are differences in interpretation of religious texts and practices among different denominations, such as Catholicism, Protestantism, and Orthodox Christianity.
In Islam, there are different schools of thought and interpretations of Islamic law, such as Sunni and Shia Islam.

The Indian State both keeps away from religion as well as intervenes in religion. This idea can be quite confusing. Discuss this once again in class using examples from the chapter as well as those that you might have come up with.

The Indian State keeps away from religion by maintaining a secular constitution that guarantees religious freedom to all its citizens. At the same time, the State also intervenes in religion to prevent religious discrimination, promote equality, and protect the fundamental rights of individuals. For example, the government has banned practices such as sati and caste-based discrimination, which were justified on religious grounds. However, this idea of secularism can be confusing as there are many challenges in implementing it effectively, such as balancing the rights of religious minorities with the need for social harmony and preventing the politicization of religion.

The British colonial government did not recognize the rights of shifting cultivators to land. As a result, they were often forced to leave their land and migrate to other areas.
The introduction of settled agriculture and the spread of commercial crops led to the destruction of forests and the depletion of soil fertility. This made it difficult for shifting cultivators to find new land for cultivation.
The imposition of revenue demands by the British led to increased pressure on land and forced the shifting cultivators to pay more taxes.

How did the powers of tribal chiefs change under colonial rule?

Under colonial rule, the powers of tribal chiefs changed in the following ways:

The Permanent Settlement was an agreement between the British East India Company and the zamindars (landlords) of Bengal, Bihar, and Orissa. Its main features were:

Fixed revenue: The zamindars were required to pay a fixed amount of revenue to the Company, which was set at 10/11th of the previous average revenue of their estates.
Hereditary right: The zamindars were given the hereditary right to collect revenue from their estates in perpetuity, as long as they paid the fixed amount.
No interference: The Company promised not to interfere in the internal affairs of the zamindars, and allowed them to manage their estates as they saw fit.

How was the mahalwari system different from the Permanent Settlement?

The mahalwari system was a method of revenue collection introduced by the British in some parts of India. It differed from the Permanent Settlement in the following ways:

Revenue was not fixed: In the mahalwari system, the revenue was not fixed, but was based on the actual income of the land each year. The revenue was collected from each village as a whole, rather than from individual landlords.
Joint responsibility: In the mahalwari system, the revenue was collected jointly from all the landlords in a village, rather than from a single zamindar.
Redistribution of land: The mahalwari system allowed for the redistribution of land among the villagers, based on their ability to pay the revenue.

Give two problems which arose with the new Munro system of fixing revenue.

The Munro system was a new method of fixing revenue introduced in the Madras Presidency by Thomas Munro, the Governor of Madras. The two problems that arose with this system were:

Over-assessment: The revenue was fixed based on the potential income of the land, rather than the actual income. This led to over-assessment, and the ryots (peasants) had to pay more than they could afford.
Loss of cultivable land: In order to increase revenue, the government encouraged the landlords to convert more land to commercial crops like cotton and indigo. This led to a loss of cultivable land, which caused problems during famines.

Why were ryots reluctant to grow indigo?

Indigo was a cash crop that was in great demand in Europe for dyeing textiles. The British government and the East India Company encouraged the landlords to grow indigo on their lands, and forced the ryots to cultivate it. The ryots were reluctant to grow indigo for the following reasons:

Low income: Indigo was a low-value crop, and the ryots had to sell it to the Company at a fixed price, which was often lower than the market price. This meant that they earned very little from growing indigo.
Labour-intensive: Indigo cultivation required a lot of labour, which was a burden on the already overworked ryots.
Soil depletion: Indigo was a demanding crop that depleted the soil of nutrients, making it less fertile for other crops.

What were the circumstances which led to the eventual collapse of indigo production in Bengal?

The following were the circumstances that led to the eventual collapse of indigo production in Bengal:

The indigo planters used oppressive methods to force the ryots to grow indigo on their lands. This caused resentment among the ryots, who were not able to grow their own crops and were forced to work for the planters.
The prices offered by the planters for indigo were low and the ryots were not able to make a decent living from growing indigo.
The planters often cheated the ryots by weighing the indigo wrongly or by mixing it with stones and sand. This led to further resentment among the ryots.
The British government in India, under pressure from British public opinion, passed a law in 1860 which regulated the conditions of indigo cultivation. This law protected the rights of the ryots and made it difficult for the planters to continue their oppressive methods.
The American Civil War (1861-1865) disrupted the supply of cotton from the United States, which led to an increase in demand for Indian cotton. This led to a shift away from indigo cultivation towards cotton and other cash crops.
The rise of nationalism in India also contributed to the collapse of indigo production. Indian nationalists, led by figures like Rabindranath Tagore and Mahatma Gandhi, encouraged the ryots to boycott indigo cultivation and to demand better conditions and fair prices for their crops.

As a result of these factors, indigo production in Bengal eventually collapsed and the planters were forced to switch to other crops.

NCERT CLASS 8 HISTORY CHAPTER 2 FROM TRADE TO TERRITORY

4. 4 What attracted European trading companies to India?

India was a hub of trade and commerce, with a long history of international trade relations and a diverse range of valuable commodities, including spices, textiles, and precious stones.
The Mughal Empire, which ruled over much of India at the time, had a liberal trade policy that allowed for foreign traders to enter and conduct business in the country.
European trading companies, such as the British East India Company, were able to establish profitable trading posts and monopolies in India, which eventually led to the colonization of the country.

What were the areas of conflict between the Bengal nawabs and the East India Company?

The Bengal nawabs and the East India Company clashed over issues of trade, taxation, and territorial control.
The nawabs saw the Company's growing power as a threat to their own authority and attempted to restrict their activities and privileges.
The Company, on the other hand, wanted to expand their influence and profit margins in Bengal, leading to conflicts over trade regulations and taxation policies.

How did the assumption of Diwani benefit the East India Company?

The assumption of Diwani gave the East India Company the right to collect revenue from the territories of Bengal, Bihar, and Orissa, which were under the control of the Mughal Emperor.
This allowed the Company to control the economic and political affairs of these regions and establish a stronger foothold in India.
The revenue collected from these territories also helped the Company to finance its military campaigns and further expand its territorial control.

Explain the system of “subsidiary alliance”.

The system of "subsidiary alliance" was a policy adopted by the British East India Company in its dealings with Indian rulers in the late 18th and 19th centuries.
Under this system, Indian rulers were required to maintain British troops in their territories, pay for their upkeep, and provide them with supplies and provisions.
In return, the British guaranteed the ruler's security and protection against external threats and internal rebellions.
This system effectively allowed the British to control and manipulate the affairs of the Indian states without having to annex them.

In what way was the administration of the Company different from that of Indian rulers?

The administration of the East India Company was centralized, bureaucratic, and aimed at maximizing profits and revenue collection.
The Company's officials were appointed on the basis of merit and qualifications, rather than social status or hereditary rights.
In contrast, the administration of Indian rulers was often decentralized and based on personal relationships and patronage networks.
Officials were often appointed based on their social status and connections, rather than their qualifications or abilities.

Describe the changes that occurred in the composition of the Company’s army.

The East India Company's army underwent significant changes over time, reflecting the evolving nature of its territorial control and military requirements.
Initially, the Company relied on a small number of European soldiers and sepoys (Indian soldiers) to protect its trading posts and commercial interests.
However, as the Company expanded its territorial control, it began to recruit more sepoys and establish a standing army.
The composition of the army also became more diverse, with soldiers from different regions and castes being recruited and trained.
Eventually, the Company's army became a key instrument of colonial control, used to quell rebellions and maintain British rule over India.

NCERT CLASS 8 HISTORY CHAPTER 1 HOW, WHEN, AND WHERE

What is the problem with the periodization of Indian history that James Mill offers?

ANSWER: The issues with James Mill's periodization of Indian history are:

Eurocentric bias and lack of understanding of Indian cultural and historical context.
Divides Indian history into three periods (Hindu, Muslim, and British) based only on the religious identity of the ruling elites, ignoring the diversity and complexity of Indian society and its rich cultural heritage.
Portrays Indian society as static and unchanging, failing to recognize the many political, social, and cultural changes that occurred over the centuries.

Why did the British preserve official documents?

ANSWER: The British preserved official documents for several reasons, including:

To ensure efficient governance and record-keeping of their rule and administration as a colonial power.
To maintain institutional memory and continuity.
To facilitate research on India's history, culture, and society.

How will the information historians get from old newspapers be different from that found in police reports?

ANSWER: The information historians obtain from old newspapers will differ from what is found in police reports in the following ways:

Newspapers provide a broader perspective on events and issues, while police reports may focus on specific incidents and individuals.
Newspapers cover a wider range of topics and provide a more nuanced view of society and politics.
Newspapers can reveal public opinion, cultural trends, and social movements that police reports may not capture.
Newspapers may have biases or perspectives that differ from those of the authorities, providing a more critical or alternative perspective on events.

Agriculture

(i) Agriculture is the practice of cultivating land, growing crops, and raising animals for food, fuel, and other products that are essential for human consumption and economic development.

(ii) The factors influencing agriculture are:

Climate: temperature, precipitation, and sunlight affect crop growth.
Soil: the type, fertility, and texture of soil influence crop productivity.
Topography: the physical features of land such as elevation and slope can affect agriculture.
Water: availability of water resources such as rivers, lakes, and groundwater is critical for crop growth.
Technology: advancements in farming practices, machinery, and irrigation systems can increase crop yield and efficiency.
Market: demand and prices for agricultural products impact the decisions of farmers.

(iii) Shifting cultivation is a traditional method of farming in which farmers clear a section of land, grow crops for a few years until the soil loses fertility, and then move on to another plot. The old plot is left fallow for a few years to regain fertility before being used again. The disadvantages of shifting cultivation are:

Soil erosion and depletion of soil fertility due to the repeated clearing of forests.
Loss of biodiversity as natural habitats are destroyed.
Vulnerability to climate change and unpredictable weather patterns.
Difficulty in market-oriented production and income generation.

(iv) Plantation agriculture is a form of commercial farming in which large-scale monoculture crops such as tea, coffee, rubber, sugarcane, and cotton are grown for export. It involves the use of capital-intensive inputs such as machinery, chemicals, and fertilizers. Plantation agriculture is prevalent in tropical and subtropical regions with adequate rainfall and fertile soils.

(v) Fibre crops are crops grown primarily for their fiber content, which is used in the production of textiles, paper, and other products. Some examples of fibre crops and the climatic conditions required for their growth are:

Cotton: requires a warm and humid climate with moderate rainfall.
Jute: grows best in a hot and humid climate with plenty of rainfall.
Hemp: can grow in a wide range of climatic conditions, but requires well-drained soil and moderate rainfall.

(i) Agriculture is a primary activity in India because it is the primary source of livelihood for a majority of the population. Around 58% of the population is engaged in agriculture and related activities, and it contributes around 17-18% of the country's GDP.

(ii) Different crops are grown in different regions due to variations in climate, soil, and topography. India has a diverse agro-climatic zone that allows for the cultivation of a wide range of crops. For example, rice is predominantly grown in the eastern and southern regions with high rainfall, while wheat is grown in the northern regions with a dry winter season.

(i) Primary activities are those activities that involve the extraction of natural resources, such as agriculture, fishing, mining, and forestry. Tertiary activities are those that provide services to people and businesses, such as banking, retail, transportation, and healthcare.

(ii) Subsistence farming is a type of farming in which farmers produce only enough food to feed themselves and their families. It is usually practiced in rural areas where there is limited access to modern technology and markets. Intensive farming, on the other hand, is a form of farming that involves the use of high inputs of labor, capital, and technology to maximize crop yields and profits. It is usually practiced in commercial farming operations.
