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 metallic 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?
