What is meant by destructive distillation of coal?
Destructive distillation of coal is a process where coal is heated in the absence of air, causing it to decompose into various volatile compounds and solid residues. This process yields by-products such as coal gas, coal tar, and coke.

What is the most common variety of coal?
Probably bituminous, the "middle grade" of coal. Lowest is lignite, which is usually only used in underdeveloped countries as it has low heat output and high pollution. Above bituminous is anthracite, an excellent, very hard (and very expensive) coal. When you ask most people to visualize a lump of coa in their mind, ninety to ninety-five percent of them will visualize bituminous.
