The solubility of gases in water increases when the temperature decreases.

Explanation:

The solubility of gases in water increases when the temperature decreases.

Why?

Gas particles have what is called an average kinetic energy #KE_(av)# which solely depends on temperature as follows:

#KE_(av)=3/2RT#

Thus, when the temperature increases, the kinetic energy will increase and therefore, the gas particles will have enough energy to escape the liquid phase, and vice versa.
