What is the usual effect of increasing temperature on the solubility of gases in liquids?
Answer and explanation
Correct answer: Solubility usually decreases
The solubility of most gases in liquids decreases as temperature rises. Gas particles gain kinetic energy when heated, so they escape from the liquid more easily. This is why warm water usually contains less dissolved oxygen than cold water. The word “usually” is important because the exact change can depend on the gas and solvent.
