Question

Cold air contains more water vapour than warm air.(true or false)​

Answer 1

Answer:

I think false

Explanation:

There's the same amount of moisture, but the relative humidity of the heated air is much less —the warmed air can “hold” a good deal more moisture than the cool air. ... It's just that, at higher temperatures, water molecules are more likely to go into the vapor phase, so there will be more water vapor in the air.

Answer 2

Answer: False

Explanation: A oft-repeated water vapor myth is that warm air can “hold” more water vapor than cool air because as the air warms its molecules move farther apart, making room for more molecules. But, saying cold air can't hold as much water vapor as warmer air is at best a metaphor for what happens.
