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.

∙ 13y agoThere is such a thing as air pressure because air has mass it creates pressure. It also keeps us balanced.

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
Which of these does the atmosphere exert pressure on?
the earths surface.
What Gases in earths atmosphere exert what on everything?
Pressure
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 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.
What makes you fart when you cough?
When you cough, you exert pressure on your lower GI which pushes air.
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.
