Fractional Distillation

Fossil Fuels are finite resources and are non renewable.
Oils are Hydrocarbons (Hydrogen and Carbon
LPG, Liquid petroleum Gas, contains Propane and brutane. Bitimen has a high boiling point. Used to make Tar
The fractioning column has a temperature gradient. Fractions contain mixtures of hydrocarbons with similer boiling points. Fractions with low boling points condense at the top of the column.
Intermolecular forces must be broken as a liquid. Heavy long chain molecules like Bitumen have strong forces of attraction so it is hard to separate them =High Boiling Point
Light short chain molecules like Petrol have weaker attractive forces and are easily separated and have low BPT's.
During boiling, intermolecular forces between molecules break but the covalent bonds do not.
Smaller chain molecules are in higher demand than smaller
