If two places have the same relative humidity, will their actual water vapour content definitely be the same?

Answer and explanation

Correct answer: No, because different temperature means different saturation capacity

Answer: A. Relative humidity is a ratio or percentage: actual water vapour present divided by the maximum possible amount at the same temperature, multiplied by 100. The saturation capacity changes strongly with temperature. For example, air at 80% relative humidity in a warm place can contain more actual vapour than air at 80% in a cold place, because warm air can hold more vapour at saturation. A is correct because equal percentages do not guarantee equal absolute moisture. B is wrong because relative humidity is not the same as actual vapour content. C is wrong because different places can have different temperatures. D is wrong because water vapour strongly affects clouds, rain, and comfort. Memory cue: same percentage does not mean same amount; always check temperature.
