# Why do gases always tend to be less soluble in liquids

Question:

Why do gases always tend to be less soluble in liquids as the temperature is raised?

Solution:

Solubility of gases in liquids decreases with an increase in temperature. This is because dissolution of gases in liquids is an exothermic process.

Gas $+$ Liquid $\longrightarrow$ Solution $+$ Heat

Therefore, when the temperature is increased, heat is supplied and the equilibrium shifts backwards, thereby decreasing the solubility of gases.
