- Describe methods of purification by the use of a suitable solvent, filtration, crystallisation, distillation
Fuel is a substance that releases energy (E.g.: Coal, Natural gas, Ethanol)
Lubricant is a substance that reduces friction between two surfaces.
Hydrocarbons are organic compounds containing carbon and hydrogen only.
Different hydrocarbons are collected at different levels according to their boiling points.
The higher they are collected the lower their boiling point.

- Suggest suitable purification techniques, given information about the substances involved
Fractional Distillation of Crude Oil:
Crude oil is a mixture of hydrocarbons. It is the major source of fuel. It is refined and separated into several very useful fractions by fractional distillation in a fractionating tower. The higher the fraction is obtained in the fractionating tower the lower its boiling point.
