# How does the temperature affect the amount of gas dissolved?

Feb 10, 2016

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 $K {E}_{a v}$ which solely depends on temperature as follows:

$K {E}_{a v} = \frac{3}{2} R T$

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.
