Question

Which is heavier, water vapour or dry air?​

Answer 1

Answer:The molecular weight of dry air is 28.97 grams per mole. Since mole per mole, dry air is heavier than water vapor, any mixture of dry air with water vapor will weigh less than pure dry air.

we can see that the main difference between the wet air an dry air comes from the level of moisture in the air. ... Moist air can make a hot day become even hotter and more uncomfortable because it limits the evaporation of moisture on the skin, while dry air can make your skin rough and chapped.
