Bitumen, fuel oils, heating oil, diesel, paraffin, petrol, LPG.
2
Q
Crude oil can be separated because the hydrocarbons in different fractions have differently sized molecules.
A
Intermolecular forces are broken during boiling.
The molecules of the liquid separate from each other as molecules of gas.
Large molecules, e.g. Bitumen, have strong forces of attraction therefore a lot of energy is needed to break the bonds
3
Q
How can transporting oil cause problems?
A
Oil slicks can damage bird feathers and can even kill them. Clean up operation use detergents which can be detrimental to wildlife.
4
