1.	The material A is a 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 and industrial fuel whereas the product F has been traditionally used for metalling the roads. (a) What could material A be ? (b) What is (i) physical state, and (ii) colour, of A ? (c) Name the processes (i) B, and (ii) C. (d) What are (i) D, (ii) E, and (iii) F ?

The material A is a 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 and industrial fuel whereas the product F has been traditionally used for metalling the roads.

(a) What could material A be ?

(b) What is (i) physical state, and (ii) colour, of A ?

(d) What are (i) D, (ii) E, and (iii) F ?
