Answer 1

Charcoal is an amorphous form of carbon. Charcoal is classified based on availability as wood charcoal, bone charcoal, and sugar charcoal. When wood is heated in a limited supply of air, it gives a soft, black, porous substance called wood charcoal. It is a bad conductor of electricity and smokeless fuel. Then comes sugar charcoal which is the purest form of charcoal and used as a reducing agent to extract metals from their oxides and the bone charcoal is obtained by destructive distillation of bones resulting in bone charcoal.
