Answer to Question 1

The distillation process involves heating the water to boiling temperature, then cooling and collecting the vapor,
which leaves the salt behind. It is important to realize that the boiling point of water can be lowered substantially
by reducing the air pressure on the water (partial vacuum). By using a partial vacuum, the amount of heat energy
required to bring the water to a boil is reduced.

Answer to Question 2

In a tank, place some fresh water on one side of a membrane and salt water on the other side. Apply pressure to
the saltwater side to force the water from the salty side through the membrane leaving the salt behind
