With increase in temperature, the solubility of most gases in water:
AIncreases
BFirst increases then decreases
CDecreases
DRemains constant
Answer & 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.
