Why is crude oil considered a non-renewable resource?

• It forms quickly

• It is unlimited

• It is primarily water

• It forms over millions of years

What is the purpose of heating crude oil in fractional distillation?

• To increase its density

• To purify it

• To turn it into a gas

• To reduce its volume

At what point do the longest chain hydrocarbons condense in the fractionating column?

• In the middle of the column

• At the top where it's coolest

• Outside the column

• Near the bottom where it's hottest
