air pressure is caused by the constant motion of air molecules
constant pressure

changes in air pressure cause wind, but the sun is the major factor in changes to air pressure.
As air becomes warmer it becomes less dense (as long as the pressure remains constant)
air pressure is caused by the constant motion of air molecules
air pressure
The atmospheric pressure has no effect on the speed of sound when the temperature is constant. The air pressure has no influence on the sound.
When air pressure is constant throughout a region of the atmosphere the region is in a state is called equilibrium.

The source of memories. APEX
Air Mass or equlibrium
factory air pressure norm is 80 psi
By using details and informations
If the volume of a container of air is reduced by one half the partial pressure of the oxygen with in the container will be doubled. If the volume of a container of gas is reduced, the pressure inside the container will increase.
warm air requires energy and energy needs a constant source
