2
Q

What is crude oil?
A
A mixture of lots of different hydrocarbons, most of which are alkanes
5
Q
What is the first stage of fractional distillation?
A
The oil is heated until most of it is evaporated into a gas it is then fed into the fractionating column
6
Q
What is the second stage of fractional distillation?
A
As the gas moves up the fractionating column the hydrocarbons condense at different points
