1. Recap: Simple Distillation
What is it used to separate?
How does it work?
Key words

2. Start mixture: 50% propanone (boiling point 58°c)
50% water with food dye (boiling point 100°c)
Big question: How could we separate these 2 liquids?
Big question: How can we test for water and propanone at the start and end of the process to prove they are there?

4. Fractional Distillation
Crude oil
Separating crude oil in industry

5. Fractional distillation
Fractional distillation is used to s _ _ _ _ _ _ _ crude oil (a m _ _ _ _ _ _) into its different parts (f _ _ _ _ _ _ _ _). Each fraction has a different use.
Because they have different b _ _ _ _ _ _ points, the substances in crude oil can be separated using fractional distillation. The crude oil is e _ _ _ _ _ _ _ _ _ and its vapours allowed to c _ _ _ _ _ _ _ at different temperatures in the fractionating column.
