Air Pressure means the measure of the force with which air molecules pushed on a surface.
it is a barometer

Not a very specific question. Could you give more details.
When we blow the aire increases in that are and the air pressure decreases forcing the thinks to move
Depends on the plane, but most can do at least a couple hundred miles on hour, also depends on altitude, airpressure, and winds.
Yes that is so. All air pressure in auto tires is measured in psi (pounds, square inch)
Heat, number of molecules, atmospheric pressure and volume Volume * Pressure = molecules * molar gas constant * Heat
The Airlift 5810 bag came with my 2007 Toyota Tundra kit, which installation instructions listed the internal pressure as a minimum of 5 PSI, maximum of 100 PSI.
The airpressure is less when at high altitude, even in a 'pressurised' airplane. Therefore the gas in drink is not as compressed, making the expulsion of the gas more rapid, through more and bigger bubbles
A mercury barometer is a 1 meter long glass tube with the top sealed and turned upside down in a bath of mercury the pressure on the surface of the bath of mercury lifts the level of the mercury in the tube dependent on atmospheric pressure.
Air pressure decreases as you go up in altitude. This is because the weight of the air above you decreases with height, leading to fewer air molecules and lower pressure. Consequently, as you ascend in elevation, there is less atmospheric pressure exerted on you.
The higher you climb up a mountain, the air pressure drops. With less air pressure on the surface of the water, it is easier for the top layer of water molecules to part off and become gas, hence the lower boiling point.
