Question

How does water vapour affect air pressure?​

Answer 1

Answer:

Warm air expands. The molecules of the warm air become less dense and hence exert less pressure. ... Water Vapour: Moist air exerts more pressure as it contains fewer amounts of nitrogen and oxygen. Dry air on the other hand, exerts less pressure as it has greater amount of nitrogen and oxygen and hence is denser.

Answer 2

Answer:

The molecules of the warm air become less dense and hence exert less presure....water vapour: Moist air exerts more pressure as it contains fewer amounts of nitrozen and oxygen. Dry air on the other hand, exerts less pressure as it has greater amount of nitrozen and oxygen and

hence is denser.
