The density of water is 1.0 (at 20C), the density of helium is 0.000178 (at 0 C) so ignoring temperature helium would have to be compressed more than 5600 fold . This also ignores state changes (like water to ice) or helium gas to liquid helium).

Since liquids do not compress as well as gasses the air would have to be under tremendous pressure to be denser than room temperature water. Just the conversion from gas to liquid of nitrogen takes a compression of 694:1.

Is air mass and air pressure the same thing?
No. An air mass is a section of the atmosphere with certain characteristics of temperature and humidity that distinguish it from nearby air masses. Air pressure is, in simple terms, how much the air is pressing down on the surface.
When altitude increases does air density?
The density of the atmosphere decreases with altitude.
Does the air increase or decrease towards the surface with a high pressure?
Air density and pressure increase nearer the surface
If the weather forecaster tells you that the pressure is falling what is the air density doing?
They tell you exactly the pressure is falling when the density of the air around us gets less, this means that air from other area's will be moving toward us to fill the air pressure up, air always moves from a high pressure area to a lower pressure area
Why the density decrees at higher altitudes?
the density decreases because their is more air pressure in lower altitudes and as you go up their is less air pressure making it hard to breath
Does air have density and pressure?
Air has both density and pressure.
How does the density of the air affect pressure?
Pressure affects the density of air by increase of pressure increases the density
How does altitude affect density and air pressure?
Altitude has a large affect on the air pressure and air density. Air density reduces with altitude and air pressure reduces with altitude as well.
What do air density and air pressure have in common?
At a given temperature, the higher the air density, the higher the air pressure.
What happens to air pressure when density decreases?
density decreases as air pressure increases
How does altitude affect density and pressure?
Air pressure decreases as altitude increases. As air pressure decreases, so does density.
How air density related to air pressure?
As air pressure pressure decreases with altitude, so does the densite of air.
How does temperature affect air density and air pressure?
When altitude rises, the air pressure and density both decrease. When temperature rises that means that more air is pushing down on it. So this means that the air pressure and density rise when temperature rises.
How Does temperature affect air pressure and air density?
When altitude rises, the air pressure and density both decrease. When temperature rises that means that more air is pushing down on it. So this means that the air pressure and density rise when temperature rises.
Why does air pressure vary?
Air pressure varies because of the differences in air's density.
What is the movement of air from an area of low air pressure to high air pressure?
density
How does increasing attitude affect air pressure and density?
as the altitude increase, the effect of gravity become more insignificant on air and the air become more disperse or thinner hence it does affect the air pressure and density by decreasing both air pressure and density of the air.
