What is crude oil primarily composed of?

• Water and minerals

• Hydrocarbons

• Oxygen and nitrogen

• Metals and salts

What is the primary purpose of refining crude oil?

• To increase its overall volume

• To make it easier to transport

• To separate it into useful substances like fuels

In a fractional distillation column, where do hydrocarbons with higher boiling points condense?

• At the very top of the column, where it is coolest

• At the bottom of the column, where it is warmest

• In the middle sections of the column

• They do not condense, remaining as gas
