Question : Name two forms of energy in which solar energy manifests itself in oceans. 
Answer :  Tidal energy and Ocean thermal energy are two forms of energy in which solar energy manifests itself in oceans.
 
 
Question : What is the scope of wind energy in India ? 
Answer :  After Germnay , U.S.A. and Denmark , India ranks fourth in world in wind power generation. Ministry of Renewable Sources of Energy is implementing the world's largest Wind Resources Assessment Programme to support wind energy programmes.
To promote utilization of wind power, a Centre of Wind Energy (C-WET) has been set up at Chennai. Out of a total capacity of 1.025 MW power of India , 380 MW is being generated at Kanya Kumari, Kerala.
 
 
Question : Describe a solar cooker. Give its advantage. 
Answer : 
Table-6
Solar cooker is a device used for cooking food with the help of solar energy. A solar cooker consists of an insulated metal box which is painted all black from inside. A plane mirror reflector is attached to the box. There is a thick glass sheet which acts as a cover over the box. The food to be cooked is placed in the box and the box is covered with the glass sheet. The cooker is placed in the sunlight and the position of the reflector is adjusted in such a way that a strong beam of sunlight falls over the cooker top. These rays pass through the transparent glass sheet and are absorbed by the black box and the containers. The use of black surface and black containers is due to the fact that a black surface absorbs more heat than any other colour. Therefore, the box and the containers absorb maximum amount of infra-red radiation from the sunlight falling on it. As a result, the temperature inside the box rises to about 100°– 140°C in two to three hours and this heat cooks the food in the containers. This type of solar cooker can be used to prepare food items which require slow heating and cannot be used for baking and frying purposes.
Advantages of Solar cooker :
a. The use of solar cooker for cooking food materials saves fuel.
b. It is cheaper method of cooking food.
c. In this method, food is cooked at comparatively lower temperature and therefore, the nutrients of food are not destroyed during cooking.
 
 
Question : What is pollution caused by fuels ? Give some details of pollution by coal, petrol and diesel. 
Answer :  i. Pollution caused by fuels : The burning of fuels releases many harmful gases and solid residues in the clean air around us. This cause danger to our lives and environment. The contamination of air with dust, smoke and harmful gases is called air pollution. Combustion of fuels is one of the major causes of pollution in atmosphere in our cities and towns. Most of the air pollution is due to the products of combustion of fuels in homes, transport and industry. The main pollutants in air are carbon monoxide, carbon dioxide, oxides of sulphur and nitrogen.
ii. Pollution caused by burning coal : Coal contains mainly the compounds of carbon, hydrogen, oxygen, sulphur, nitrogen etc. and some free carbon. This leads to respiratory troubles, headache, dizziness, unconsciousness, etc.
a. Combustion of coal, in the presence of insufficient supply of air liberates carbon monoxide. Carbon monoxide is very dangerous. This leads to respiratory troubles, headache, dizziness unconsciousness etc.
b. Coal contains compounds of sulphur and nitrogen. These compounds on combustion give oxides of sulphur and nitrogen which are corrosive and poisonous. Sulphur dioxide is very irritating and affects our lungs.
c. When coal is burnt, a large amount of smoke is also produced in air. The smoke contains some un-burnt particles. These particles, when inhaled, create breathing problems.
iii. Pollution caused by Burning of Petrol and Diesel : The major cause of air pollution in big towns and cities it's the gases produced by the burning of petrol and diesel oil in the internal combustion engines of cars, scooters, buses, trucks, motorcycles and other heavy vehicles. Methods of control the Pollution caused by Vehicles : It is difficult to control the air pollution caused by burning of petrol or diesel than those caused by burning of coal. This is due to the fact that petrol an diesel are burnt in moving vehicles. It is very difficult to control air pollution produced by these vehicles because they keep moving from one place to another.
Scientists are working with full strength to devise methods to control pollution.
Some methods to decrease the pollution created by burning of petrol and diesel are :
a. The condition of engines of the vehicles should be well maintained and regularly checked so the complete combustion of fuel takes place in the engines. This will decrease the pollution due to incomplete combustion of petrol and diesel.
b. To avoid lead pollution in the environment, car engines should be redesigned so that theses can run on unleaded petrol.
c. The exhaust gases before releasing into the air be treated with catalysts like platinum so that unwanted products are converted into harmless compounds.
d. There should be proper check of pollution causing vehicles. The law should be followed strictly to get pollution check for all vehicles.
e. Vehicles should be used only when absolutely necessary. For short distance, habit of walking should be followed.
 
 
Question : Compare and contrast fossil fuels and the sun as source of energy. 
Answer :  i. Both are natural sources of energy.
ii. Both are widely used sources of energy.
iii. Least technology is required to get energy by any of the sources.
Contrast :
i. Sun's energy can be used only during day but fossil energy can be sued any time during day or during night.
ii. Solar energy is almost free where, as fossil energy costs much.
iii. Infinite amount of solar energy is available almost free of cost whereas there is a limited stock of fossil fuel.
iv. Solar energy is renewable source of energy where as it takes millions of year to produce fossil fuel.
v. Solar energy is totally pollution free where, as fossil fuel produces a lot of pollution.
