Fractional distillation

What is crude oil?

• A covalent bond

• An oil that is used for covalent structures

• Product of cracking

• A finite resource that is used to produce fuels and other chemicals

Answer explanation

Crude oil is also a fossil from deep underground

Short chain hydrocarbons have a…

• High boiling point

• Hard structure

• Low boiling point

• Cylinder shaped structure

Answer explanation

What happens when the crude oil is put into the chamber?

• It gets heated and it turns into a gas which then evaporates

• It heats up and then condenses

• It cools down and sinks to the bottom

Answer explanation

In the fractionating column what is temperature like at the top and bottom? Select two answers.

• It’s hotter at the top

• It is cooler at the bottom

• It is cooler at the top

• It is hotter at the bottom

Answer explanation

As soon as the gas reaches a part of the column that has a lower temperature than it’s boiling point they’ll condense into a liquid 

• True

• False
