The blended coal mass is heated for 12 to 20 hours for metallurgical coke. Thermal energy from the walls of the coke chamber heats the coal mass by conduction from the sides to the middle of the coke chamber. During the coking process, the charge is in direct contact with the heated wall surfaces and develops into an aggregate "plastic zone".

CBSE Class 8 Science Chapter 5 Coal and Petroleum Objective Questions

Solution: Coal gas is obtained by the destructive distillation of coal. The destructive distillation process involves heating of powdered coal in the absence of air. The composition of coal gas varies but the main components are hydrogen, methane and carbon monoxide. Thus, the assertion is correct but the reason is an incorrect statement. 19.

Process of Coking. Coke is a solid fuel made by heating coal in the absence of air so that the volatile components are driven off. The process of heating coal in this manner is referred to as carbonization or coke making. The chemical composition alone cannot be used to predict whether a coal is suitable for coking.
