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
