With increase in temperature, the solubility of gases in liquids, at fixed pressure____________________?
Correct answer: B. Decreases
- A. Increases
- B. Decreases
- C. Remain same
- D. Either A. or B., depends on the system
Explanation
For most gases, dissolution in a liquid is exothermic, so increasing temperature drives the gas out of solution and reduces its solubility at fixed pressure. This is why warming carbonated liquids promotes gas release.
