Fractional Distillation:

When a _________ turns to a gas it is called ____________, the ____________where all of a liquid will turn to gas is called the boiling point. Different liquids have different___________. ____________liquids by their boiling point is called__________________________.

 

This diagram represents a fractional distillation column

1.What is the raw material that goes into the column?

________________________________________________ 2.Where is the hottest part?  ________________________________________________

3.Where is the coldest part? _________________________________________________

Small molecules like gases evaporate more easily Would you expect them to be found at the top or the bottom of the column? _______________________________________________________________________________________   Name two other productions from the fractional distillation of crude oil? _______________________________________________________________________________________
