Which statement is correct about the relationship between atmospheric water vapour and temperature?
Answer and explanation
Correct answer: Warm air can hold more water vapour
For a given pressure, warmer air has a greater capacity to contain water vapour before becoming saturated. If moist air cools to its dew point, saturation is reached and condensation may form clouds, fog or precipitation. Therefore option D is correct. This does not mean warm air must always be humid; actual humidity also depends on how much vapour is present. The other statements are scientifically false.
