The substance W is a folssil fuel . It occurs deep below the ground in certain areas of the earth. Another fossil fuel X is found trapped above the deposits of W. When W is subjected to a process called Y, then a number of different products are collected at different temperature ranges which are put to different uses. A special grade of product Z obtained in this way is used as aviation fuel in jet aeroplanes.
b) What is physical state of (i) W, and (ii) X ?

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 ?
