Coal
The educational resource shows information about the coal: coal is a light, black substance which comes from the fossilization of vegetable matter. Coal is used as an industrial fuel, in power stations and in home heating. There are 4 types of coal: anthracite, bituminous coal, lignite and peat.You can see how they are formed in the following animation.

Chemical energy
The educational resource shows information about the concept of chemical energy: chemical energy is what is produced in chemical reactions. An energy cell or a battery possess this type of energy. The gas burning in a cigarette lighter shows how the chemical energy contained in the gas is transformed into light and heat.
