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

    Answer:

    The dissolution of a gas in a liquid is an exothermic process (heat is released) Gas + Solvent   Solution; H = ? ve According to Le-Chatelier's principle, increase of temperature would shift the equilibrium in the backward direction. Thus, solubility of the gas in solution would decrease with the rise in temperature.
