Explain the use of petroleum as an energy resource and as an industrial raw material. (2011 OD)

Hide | Show

Answer :

The use of petroleum as a source of energy:

  1. It is used as a fuel for internal combustion engines in automobiles.
  2. It is used as a fuel for railways and aircrafts.
  3. It provides fuel for heat and lighting.

The use of petroleum as an industrial raw material:

  1. It is used as lubricant for machinery.
  2. It is used as raw material for a number of manufacturing industries, for example, chemical industry.

Its numerous by-products are used in petrochemical industries such as fertilizer, synthetic rubber, synthetic fibre, medicines, vaseline wax, soap, cosmetics etc.

Distinguish between conventional and non-conventional sources of energy. (2013 D)

Hide | Show

Answer :

Energy sources can be classified as conventional and non-conventional sources.

Conventional Sources

Non-conventional Sources

(i) They have been in use since ages.

(i) The technology for their large-scale development is relatively new.

(ii) Except hydel power they are exhaustible or non-renewable, e.g., coal, petroleum and natural gas.

(ii) They are inexhaustible sources of energy, e.g., solar, wind and tidal energy.

(iii) These non-renewable resources create pollution.

(iii) They are pollution-free, therefore are eco­friendly.

(iv) Except water, all other sources of energy are available in limited quantities.

(iv) They are freely and abundantly available in nature.

(v) It is costly.

(v) It is a cheaper source.

(vi) Because of their limited availability and exhaustible nature, we cannot depend on them for a long time.

(vi) Because of their abundant availability, they are dependable sources. Therefore, they are called our future energy resources.

Explain any three steps to be taken to conserve the energy resources. (2011 OD)

Hide | Show

Answer :

  1. We need to develop a sustainable path of energy development, i.e., increased use of renewable or non-conventional energy resources.
  2. We have to adopt a cautious approach for the judicious use of our limited energy resources.
  3. As concerned citizens we can do our bit by using public transport systems instead of individual vehicles, switching off electricity when not in use, using power saving devices etc.

What is the use of manganese? Name the largest manganese-ore producing state of India. (2012 D)

Hide | Show

Answer :

Manganese is mainly used in the manufacturing of the following items:

  1. Steel (nearly 10 kg of manganese is required to manufacture 1 tonne of steel).
  2. Ferro-manganese alloy
  3. Bleaching powder
  4. Insecticides and paints

Odisha (Orissa) is the largest producer of manganese-ore in India.

Why is energy required for all activities? How can energy be generated? Explain. (2014 D)

Hide | Show

Answer :

Energy is needed to cook, to provide light and heat, to propel vehicles and to drive machinery in industries. Energy is a basic requirement for economic development. Every sector of the national economy—agriculture, industry and transport—commercial and domestic needs inputs of energy.
Energy can be generated from fuel minerals like coal, petroleum, natural gas, uranium and from electricity. Conventional sources like firewood and cattledung cakes are most commonly used in rural India to generate energy.

‘Environmental degradation has been seen everywhere/ Explain any three values that can help to prevent environment degradation. (2014 D)

Hide | Show

Answer :

Three values that can help to prevent Environmental Degradation:

  1. We must ensure sustainable and equitable use of resources without degrading the environment or risking health or safety.
  2. We must raise awareness and consciousness among people about the importance of judicious use of resources to prevent degradation of land, water, vegetation and air.
  3. The following measures must be adopted to prevent environmental degradation:
    • Minimising use of water for processing by reusing and recycling it.
    • Smoke can be reduced by using oil or gas instead of coal in factories.

Almost all machinery can be redesigned to increase energy efficiency and reduce noise.

Which is the most abundantly available fossil fuel in India? Mention its different forms. (2015 OD, 2014 OD, 2008)

Hide | Show

Answer :

The most abundantly available fossil fuel is Coal.
There are four types of coal:

  1. Anthracite. It is the highest quality hard coal. It contains more than 80% carbon content. It gives less smoke.
  2. Bituminous. It is the most popular coal in commercial use and has 60-80% carbon content. Metallurgical coal is high grade bituminous coal and is of special value for smelting iron in blast furnaces.
  3. Lignite. It is a low grade brown coal. It is soft with high moisture content.

Peat. It has a low carbon and high moisture content. It has low heating capacity and gives lot of smoke on burning.

How is the mining activity injurious to the health of the miners and environment? Explain. (2015 D)

Hide | Show

Answer :

Adverse effect on health: The dust and noxious fumes inhaled by miners make them vulnerable to pulmonary diseases.
The risk of collapsing mine roofs, inundation and fires in coal mines are a constant threat to miners.
Adverse effects on the environment:

The water sources in the region get contaminated due to mining.

Dumping of slurry and waste leads to degradation of land, soil and increase in stream and river pollution. Stricter safety regulations and implementation of environmental laws are essential to prevent mining from becoming a ‘killer industry’.

In the present day energy crisis what steps will you like to take for saving energy? (2015 D)

Hide | Show

Answer :

Energy is required for all activities. It is needed to cook, to provide light and heat, to propel vehicles and to drive machinery in industries.

  1. Energy is the basic requirement for economic development.
  2. Every sector of national economy — agriculture, industry, transport and commerce needs greater inputs of energy.
  3. In the domestic sector also, energy demands, in the form of electricity, are growing because of increasing use of electrical gadgets and appliances.

We have to adopt a cautious approach for the judicious use of our limited energy resources. So conservation of energy should be done at all levels. Increased use of renewable energy resources, e.g., solar energy, hydel power, etc.
We, as concerned citizens can help conserve energy in the following ways:

  1. Using more of public transport system instead of individual vehicles.
  2. Switching off electrical devices when not in use.
  3. Using power saving devices.
  4. Using non-conventional sources of energy such as solar energy, wind energy etc.
  5. Getting the power equipment regularly checked to detect damages and leakages.

How can solar energy solve the energy problem to some extent in India? Give your opinion. (2015 OD)

Hide | Show

Answer :

Reasons:

  1. India is a tropical country and gets abundant sunshine.
  2. It has enormous possibilities of tapping solar energy.
  3. It is an inexhaustible source of energy which is freely available in nature.
  4. It is a cheaper source of energy and is fast becoming popular in rural and remote areas.
  5. Photovaltic technology is available which converts sunlight directly into electricity.
  6. Because of its abundant and free availability in all parts of India in addition to its ecofriendly nature, solar energy is called the energy of future.

Also use of solar energy will minimise the dependence of rural households on firewood. It will contribute to environmental conservation and reduce pressure on conventional sources of energy.
