The amount of pressure the atmosphere has varies from location to location. The internationally accepted standard atmospheric pressure is approximately 14.696 pounds per square inch (psi). This pressure is that which is measured for the altitude and location of Paris, France and is used in relevance.

What kind of pressure does a column of air exert on the air or surface below it?
air pressure
Cold air exerts more blank than warm air?
air molecules in cold air exert more pressure because they are closer together and collide more often
Why does air exert pressure?
Air exerts pressure in the same way that water exerts pressure on a diver. Air has weight, and because we are at the bottom of a blanket of air that surrounds the earth, the weight of that air is pressing down on us (creating pressure). If you go under water, you'll feel the additional pressure created by the weight of the water above you.
Does cold air exert more pressure?
It depends on the situation. In a contained vessel (eg a tyre), then hot air would exert a higher pressure. In general outside the pressure is (fairly) constant, and it is the density which changes with temperature. Imagine if this weren't true; you could have two pockets of air next to each other at different temperatures, and thus also at different pressures. In reality this leads to the pressure region expanding (and so decreasing in pressure), squashing the lower pressure region (increasing its pressure). This would continue until the pressures were the same in both regions.
What is the difference between pressure and atmospheric pressure?
Atmospheric pressure is a unit of measument, and measure the pressure of the air. Much like the deeper you go in the ocean the higher the pressure is. You are actually on the bottom of an ocean of air, the higher up the less atmospheric pressure and eventually there is non when you reach outer space.
What kind of pressure does a column of air exert on the air or surface below it?
air pressure
Does air exert pressure on air or mercury?
Yes. (see - barometer)
Can compressed air exert pressure on things?
nimple
What happens if air does not exert pressure?
Depends on how you do that - but most are fatal.
What happens if the air does not exert pressure?
Depends on how you do that - but most are fatal.
What pressure does cold air exert?
Cold air exerts a low pressure. That is why cold air falls and hotter air rises above it.
Dose air in the atmosphere exert pressure on earths surface?
Yes. Atmospheric pressure is the pressure caused by air when it exerts pressure on the surface of earth.
Why do fluid create pressure?
Fluids have a higher density than air and therefore exert more pressure than air.
Why does water exert more pressure than air?
Water is more dense than air is.
Does gas molecules in air exert pressure on the objects they surround?
Yes, Hence bouyancy.
Why doesnt pressure exert on gasses?
You have a misconception... Pressure can be definitely exerted on gas. You might have heard of air compressor? Pneumatic cylinder? these elements exert pressure on air(Gas). Free air from atmosphere is sucked inside then pressurized & used for many applications. Please go through working principles of these elements.
Does air exert any pressure?
There is about 2 ton of air on every square foot of the Earth (less at high altitudes)
