Chemical vs Physical Changes
• Molecular structure changes
• Molecules DON’T disappear they are rearranged to form a new compound
• EX. Combustion
• Molecular structure remains the same
• Ex. Evaporation Condensation
Chemical Changes Physical Changes

Fractional Distillation
• Using heat to separate any mixture into its various components

Fractional Distillation of Crude
• Separates the mixture of crude oil into various hydrocarbons

How does it work?
• Crude oil is pumped in from storage vats.
![Page 6: Fractional Distillation](https://reader033.vdocuments.mx/reader033/viewer/2022061617/568167b0550346895ddd0047/html5/thumbnails/6.jpg)
• Crude oil enters furnace and is heated. • Hydrocarbons separate at various temps.

Fractions evaporate/condense at different boiling points based on size of hydrocarbon

Fractions are placed in separate containers and further refined if needed

Why is there a perpetual flame at the top of the distillation
tower?
