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