Answer:

A fuel is any material that can be made to react with other substances so that it releases energy as heat energy or to be used for work. ... The heat energy released by reactions of fuels is converted into mechanical energy via a heat engine.

The main fossil fuels are coal, natural gas, and crude oil. They occur in all three states of matter. Coal is in solid form, natural gas is a gas, and crude oil is in liquid state. Generally, fossil fuels are non-renewable sources which mean that their reserves can be depleted from the earth's surface.
