With increase in temperature, the solubility of most gases in water:

  1. Increases
  2. First increases then decreases
  3. Decreases
  4. Remains constant
Show answer and solution

Correct answer: C. Decreases

Dissolution of a gas in water is exothermic (condensation of gas into liquid). By Le Chatelier, raising T shifts the equilibrium back toward the gaseous phase — solubility decreases. This is why hot industrial cooling water has low dissolved O₂.
