Fossil fuels are finite resources and are non-renewable because they are no longer being made or being made slowly (finite) and they are being used up faster than they are produced.
Crude oil, gas and coal are fossil fuels.
Crude oil is a mixture of many hydrocarbons. The finite nature of crude oil has problems associated with it such as finding replacements and all the readily extractable resources will be used up in the future.
Fractional distillation is a process that can seperate crude oil into useful products called fractions. Fractions that include LPG, petrol, diesel, paraffin, heating oil, fuel oil and bitumen.
Fractional distillation works by heating up the crude oil until its mostly a gas and enters a fractionating column. The column contains a temperature gradient so it is hot at the bottom and cooler towards the top. Crude oil can be seperated because of the difference in boiling points. Fractions contain a…
