Answer:
Humid air is lighter so it has lower pressure
Explanation:B.) humid air is lighter, so it has lower pressure
Explanation:
Humidity is related to air pressure in that, a humid air is lighter and it has very low pressure.
Air is heavier than water vapor.
The main component of humid air is water vapor.
Water vapor is mostly water in its gaseous form
We know that for a single mole of water, the mass is 18g
Air is a mixture of gases with Nitrogen gas dominating.
A mole of nitrogen gas has a mass of 28g.
We can see that air that is humid i.e contains more water vapor is lighter and it has a lower pressure.
