Question

How does the temperature affect the amount of gas dissolved?

Answer 1

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.
