Hint: Graphite is a form of Carbon; it was first discovered in Cumbria in north England. It is a mineral that forms when carbon is subjected to heat and pressure in earth’s crust and in the upper mantle. It is of medium Gray colour.

Complete answer:
The use of graphite is for making lead pencils, electrodes of electric furnaces, as a moderator in nuclear reactors, as a lubricant in machinery.
Graphite is a component of carbon. It has varied other roles in the environment.
Charcoal: in removing offensive odour from air, in removing fused oil from crude spirit, in decolourising sugar syrup, in gas mask etc.
Carbon black: for making printing inks, black paints, Indian inks, boot polishes and ribbons of typewriters.
Coal: it is a crude form of carbon. As a result of slow decomposition of vegetable matter under the influence of heat, pressure and limited supply of air, it leads to production of coal in nature. The anthracite which burns with non-smoky flame is superior quality. Bituminous burns with smoky flame and is hard stone, by burning substances rich in carbon content such as kerosene, petroleum turpentine oil, acetylene etc in a limited supply of air Lamp black or carbon black it is obtained.

Since the 1950s chemicals have been produced from coal. Coal gasification to produce syngas is the main route of these products. Coal can be used as a feedstock in the production of a wide range of chemical fertilizers and other chemical products.
