The world's known coal reserves are expected to last for about :

The fossil fuel P is formed under the earth by the decomposition of vegetable matter lying under water by the action of anaerobic bacteria. The major component of fuel P is Q. The fossil fuel P is used as a source of gas R needed to manufacture nitrogen fertilisers . When P is filled in metal cylinder and used as a fuel in motor vehicles, it is called S. What are P, Q , R and S ?

The material A is fossil fuel which is extracted from the earth. It is said to be formed from the buried , large land plants by a very slow process B. When A is heated in the absence of air in a process called C, then it gives three products D, E, and F. The product D is used as a reducing agent in the extraction of metals the product E is used as an industrial fuel whereas the product F has been traditionally used for metalling the roads . b) What is (i) physical state , and (ii) colour of A ?

Fossil fuels are at the verge of getting exhausted. It is because of their non-replenishment, increasing demand, increasing population and more energy dependent technologies. Therefore, one has to look up to the sources which can be regenerated and cause the minimum possible environmental damage. ''I'' am a fossil fuel that is very important for daily use. I am non-renewable source and regarded as the cleanest source of energy. I am found deep inside the earth in the gasous state. Who am “I"?
