As the pressure of a gas increases at constant temperature, the volume of the gas decreases.

If you were a diver and you wanted to take an oxygen tank with you, what would you do?

Increase the temperature of oxygen in the tank, so that the cold oxygen doesn't damage the lungs.
Decrease the pressure of oxygen in the tank, so the tank doesn't explode.
Increase the temperature of the oxygen and decrease the pressure, so the volume stays the
same.
Pressurize the oxygen, so more of it can fit in a tank of a manageable size.
Decrease the temperature of oxygen, so that it doesn't escape from the tank.

Explanation

A diver would want to take a lot of oxygen without letting the tank get too bulky.
