Coal is a complex mixture of compounds of carbon, hydrogen and oxygen and some free carbon. Small amounts of nitrogen and sulphur compounds are also present in coal. It is found in deep coal mines under the surface of earth. Coal is used as a fuel for heating purposes in homes and industries, in thermal power plants for generating electricity, in the manufacture of coal gas, petrol and other synthetic natural gas. Coal produces lot of smoke which pollutes the air.
Charcoal is prepared from wood. When wood is burnt in a limited supply of air, then water and other volatile materials present in it get removed and a black substance 'charcoal' is left behind. Charcoal is mainly carbon. Charcoal is used as a fuel for domesic purpose due to its high calorific value and it does not produce smoke while burning. It is easy to handle and convenient to use.
