CHAPTER -5 COAL AND PETROLEUM

_________________________________________________________________

  

Question 1.What are the advantages of using CNG and LPG as fuels?
Answer: The advantages of using CNG and LPG as fuels are:

They burn with a smokeless flame and so does not cause any pollution.

Question 3.Describe how coal is formed from dead vegetation. What is this process called?
Answer:Millions of years ago, trees, plants, ferns and forests got buried below the rocks, soil and sand due to natural processes like flooding, earthquake, etc. Slowly, as more soil deposited over them, they were compressed. This led to the conditions of high pressure and heat. These conditions along with the anaerobic conditions turned the carbon-enriched organic matter of wood into coal.
This slow process of conversion of wood into coal is called carbonisation.

Question 4.Fill in the blanks.
(a) Fossils fuels are coal, petroleum, and natural gas
(b) Process of separation of different constituents from petroleum is called refining
(c) Least polluting fuel for vehicle is CNG

Question 5. Tick True/False against the following statements.
(a) Fossil fuels can be made in the laboratory.                           [False]
(b) CNG is more polluting fuel than petrol.                             [False]
(c) Coke is an almost pure form of carbon.                             [True]
(d) Coal tar is a mixture of various substances.                          [True]
(e) Kerosene is not a fossil Fuel.                                        [False]

Question 6.Explain why fossil fuels are exhaustible natural resources.

Answer:Fossil fuels take millions of years to be formed. They are limited in nature and cannot be replenished easily, once consumed. Hence, they are considered as exhaustible natural resources.

Question 7.Describe the characteristics and uses of coke.
Answer:Characteristics of coke: Coke is 98% pure carbon. It is a tough, porous and black substance. It pro-duces a very little smoke.
Uses of coke: Coke is very useful as fuel. It is a good reducing agent. It is widely used in metallurgical processes to reduce metals from their oxides. It is used for producing water gas.

Question 8.Explain the process of the formation of petroleum.
Answer:Petroleum is formed by the burial of aquatic plants and animals below the sea bed. The marine animals and plants died thousands of years ago and settled down in the bottom of sea. In anaerobic conditions, microorganisms decompose this organic matter. Due to high pressure and heat, the dead remains of tiny plants and animals were slowly converted into petroleum

 F.Long Answer Type Questions

Question 1.What are the reasons responsible for poverty in India?
Answer:The main reasons responsible for poverty in India are:

1. Defective Development Strategy:
In India strategy a contradiction of poverty with growth is seen because the benefits of development are limited to only some people.

As a result of it the poor are becoming poorer and the rich richer. Opportunities for further progress are available to the educated and people who have facilities while the poor are unable to obtain even higher and technical education, due – to scarcity of wealth. The Government has made job opportunities available but its progress is very slow.

2. Unemployment:
Unemployment in India is widespread. According to an estimate there are about 5 crore unemployed people in India. The number of unemployed persons is increasing continuously, which is an important factor for poverty. In rural areas disguised unemployment also exists along with unemployment and seasonal unemployment. The increasing number of unemployed people decreases the productivity of individuals and the standard of income.

3. Low Per Capital Income:
In India poverty is expanding because of low per capital income. As compared to the developed countries of the world the per capital income in India is very low. According to the report of the World Bank of the year 2004 the per capital income in India is only 480 Dollars (about Rs. 24,000/-). Low per capital income is the chief reason of poverty in India.

According to the census of 2001 the annual growth of population in India during the decade of 1991 2001 was 1.93. This leads to low per capital income and consumption and low standard of living. It promotes poverty.

5. Use of Natural Resources:
Minerals, forest wealth and .human resources etc. in India are in abundance. But till now they have not been used in a proper way. The scanty use of natural resources is also a reason of poverty.

6. Inflation and Price Rise:
A huge amount of wealth is spent on the accomplishment of the development tasks. It generates inflationary pressure on the economy and the prices start increasing. As a result the problem of poverty becomes more severe.

7. Low Standard of Technical Knowledge:
There s scarcity of the facilities for the technical education and research etc. in India. About 36 per cent of the population of India is illiterate. The productivity declines as there is lack of technical education and facilities of training.

8. Low Productivity:
In India the productivity is low, therefore, proper returns from tire resources are not obtained and the people remain poor. Low productivity in the agriculture sector is the chief reason for rural poverty.

9. Uncertainty in Agriculture:
The Indian economy is based on agriculture, which depends on monsoon for irrigation. Monsoon is always uncertain due to which there have been fluctuations in the agricultural production. These natural calamities affect agricultural production adversely, which results in poverty

10. Lack of Means of Transport and Communication:
In India 1 the rapid growth of agriculture, industries, and the tertiary sector is not possible means of transport and communications are not fully developed
