Why does relative humidity usually increase when air cools?

Answer and explanation

Correct answer: Air capacity to hold water vapour decreases

Correct answer: A. Relative humidity depends not only on the amount of water vapour but also on the air’s capacity to hold vapour. Cooling reduces this capacity. If the air initially contains the same amount of vapour, that unchanged amount becomes a larger fraction of the reduced capacity. Thus relative humidity rises, and if cooling continues to the dew point, the air becomes saturated and condensation may begin. B is unrelated because seawater freshness does not determine atmospheric relative humidity. C is incorrect because cooling does not necessarily make wind speed zero. D is the opposite of the usual cooling situation and does not explain the increase. Remember: cooling shrinks the vapour-holding capacity; the same vapour then occupies a larger percentage.
