In which situation can relative humidity decrease even if water vapour amount does not change?

Answer and explanation

Correct answer: When temperature rises

Correct answer: A, when temperature rises. Relative humidity is the amount of water vapour actually present compared with the maximum amount the air could hold at the same temperature, expressed as a percentage. If the actual vapour amount stays constant but air warms, its moisture-holding capacity increases. The same vapour then represents a smaller percentage of the possible amount, so relative humidity decreases. B is wrong because cooling reduces capacity and usually raises relative humidity when vapour amount is unchanged. C is wrong because at the dew point the air reaches saturation, so relative humidity is about 100 percent. D is wrong because saturated air also has relative humidity of about 100 percent, not a decrease. A simple example is a warm afternoon: the air may contain the same water vapour as earlier, yet its relative humidity can be lower. Do not confuse relative humidity with the actual amount of vapour.
