Why are fossil fuels described as finite resources and non-renewable?
They never run out.
Finite resources are no longer being made or are being made very slowly. Non-renewable energy resources are used up faster than they can be replaced.
They run out eventually.

In the fractional distillation of crude oil:- Crude oil is The fractionating column has a temperature ( at the top and at the bottom). Fractions containing of hydrocarbons are obtained. The fractions contain many substances with boiling points. Fractions with low boiling points exit from the of the column. Fractions with high boiling points exit from the of the fractionating column.
LPG contains and

It'll make the clouds sad.
The hydrocarbons in crude oil can be separated by fractional distillation because the bonds between carbon and hydrogen atoms within a hydrocarbon are than the intermolecular forces between hydrocarbon molecules.
Intermolecular means during boiling, intermolecular forces are but bonds are not.
Intermolecular forces between large hydrocarbon molecules are than those between smaller hydrocarbon molecules.

Cracking crude oil fractions:-
Coverts alkane molecules into smaller molecules . Uses an catalyst at a temperature. The alkene molecules made are useful because they can be used to make
When crude oil is distilled the volume of each fraction is not the same, we get too many hydrocarbons than are needed and not enough short-chain hydrocarbons (e.g. ) to meet the demand for them. Cracking helps an oil refinery match its supply of useful products (such as petrol) to the for them.
