Dry air is "heavier" than moist air, that is, it is denser. The water molecules in humid air do not fit in between "air" molecules (diatomic nitrogen and oxygen in a 79:21 ratio), they replace them, as per Avogardo's number of molecules in a mole of a gas. One molecule of diatomic nitrogen has a mass of 32 AMU and of diatomic oxygen, 28 AMU. A water molecule only has a mass of 16 AMU. Don't believe it? Think about it: a high pressure system is dry air and is higher pressure because it is a sinking air mass. It sinks because it is heavier.

What is sinking air dry weather and few clouds?
Sinking air, combines with dry weather and only a few clouds are indicators of a cold front. Cold air is heavier and more dense than warm air.
What brings dry clear weather?
Clear weather is caused by dry winds and high pressures. Low pressures are an indication of rising air, which carries moisture aloft and causes rain. Damp maritime air, that which comes from over warn oceans, brings moisture onshore and causes rain.
Is bromine gas heavier than air?
The bromine vapors are heavier than air.
Why do wet clothes dry faster on a hot day than on a cold day?
The moisture from the clothing evaporates, taking surface heat with it and thereby cooling the skin.
Is a high pressure center characterized as cool dry air or warm dry air?
Cool dry Air
Is moist air heavier or lighter than dry air?
Moist air is heavier than dry air, because of the water.
Out of dry and wet air which is heavier?
Moist air weighs less than dry air at the same temperature. This is because the density of diatomic Oxygen and Nitrogen is greater than water vapor (H2O).
Does a nail rust faster when the air is damp or dry?
it rusts faster when it is damp cause the moisture of the damp and oxygen when they meet they create rust
Who is heaver nitrogen or air?
Dry air is about 80% nitrogen. The remaining 20% consists mostly of things that are heavier than nitrogen, so dry air is very slightly heavier than nitrogen.
Why is dry air heavier than wet air?
The 'wetness' in the air creates a more dense 'air particle' which creates humid areas and such.
Can dry ice float a hot air balloon?
No. Dry ice is frozen carbon dioxide, which is heavier than air, so wont float a balloon.
Does a millipede like a dry or damp habitat?
damp
What is sinking air dry weather and few clouds?
Sinking air, combines with dry weather and only a few clouds are indicators of a cold front. Cold air is heavier and more dense than warm air.
Air pressure is highest when the air is?
Cool and dry. I do not completely agree with the answer above. When air has more moisture in it, it is heavier. When it is colder it is denser and heavier. Air planes have more "lift" in higher humidity and hot air is what makes balloons rise. In weather it appears that air is dry when the pressure is high...more rain when the pressure is low. That is a factor of weather patterns, not properties of air.
