allerySolubility of gases in liquids generally:
AIncreases with both temperature and pressure
BDecreases with temperature, increases with pressure
CIncreases with temperature, decreases with pressure
DIs independent of temperature and pressure
Answer & Solution
Correct answer: B. Decreases with temperature, increases with pressure
Gas dissolution is exothermic
→ solubility **falls with T** (why aquatic life prefers cold water).
Higher pressure → more gas particles striking surface
→ **solubility rises with P** (Henry's law).
