Air pressure.
The measure of force with which air molecules are pushing on earths surface is called air pressure. At sea level, at what we call standard atmospheric pressure, the pressure is about 14.696 PSI, or about 29.92 inHg, or about 760 mmHg. This is 101.324
Answerthe reason is that the molecules in air push in all directions down,up, and sideways. The air pushing down on top of your desk is balanced by the air pushing up on the bottom of your desk.
Other than the force of the air on the windscreen as the aircraft moves forward through the air (a function of speed and air density), the primary affect of air pressure on window glass in an aircraft is from the force of cabin air pressure pushing out against the window. This force can be in the neighborhood of 8 pounds per square inch in the average commercial aircraft. Because of this rather significant force, windows in pressurized aircraft generally are small and sturdily built.
If they are both under the same pressure and are the same in volume, then, yes, warm air has fewer molecules

You're looking for "air pressure", but you haven't described it correctly.The pressure is not the force pushing on the surface.It's the (force pushing on the surface) divided by the (area of the surface).
it is AIR PRESSURE
This force is called atmospheric pressure, the force is measured per unit area because the bigger the area the more molecules hit. It is 14.7 pounds per square inch ("psi")

The difference is that Low air pressure has less air molecules pushing down in one area and high air pressure has more air molecules pushing down in one area.
The difference is that Low air pressure has less air molecules pushing down in one area and high air pressure has more air molecules pushing down in one area.
The difference is that Low air pressure has less air molecules pushing down in one area and high air pressure has more air molecules pushing down in one area.
One force that affects and object is air pressure which is the force pushing on an area or surface.
The measure of the force exerted by air molecules on a surface per unit area is air pressure.
