Why is crude oil considered a finite resource?

• It is produced quickly

• It is abundant

• It is formed over millions of years

• It is renewable

What is the purpose of fractional distillation?

• To mix different hydrocarbons

• To separate hydrocarbons based on boiling points

• To cool down crude oil

• To add impurities to crude oil

What happens to hydrocarbons with the longest chains during fractional distillation?

• They evaporate completely

• They condense quickly and drain out early

• They remain in gaseous form

• They rise to the top of the column
