In which condition can a gas come out of a liquid more quickly?
Answer and explanation
Correct answer: When pressure is decreased
Lowering the pressure above a liquid lowers the equilibrium solubility of a dissolved gas. The liquid then contains more gas than is favoured at the new pressure, so gas escapes until a new equilibrium is reached. Therefore A is correct. Increasing pressure generally keeps more gas dissolved instead of causing rapid release.
