If air did not exert pressure, objects would not experience resistance or buoyancy as they move through it. This would result in a lack of stability and support for structures, making it difficult for living organisms to survive. Additionally, weather patterns would be drastically altered, as air pressure plays a key role in the distribution of heat and moisture across the planet.
Gas particles exert pressure on their container by colliding with the walls of the container in random directions. These collisions transfer momentum, causing the walls to experience a force per unit area, which we perceive as pressure. The greater the number of collisions per unit area and the faster the particles are moving, the higher the pressure.
Cold air exerts a lower pressure compared to warm air because the molecules in cold air are moving more slowly and are closer together. This results in a decrease in the air pressure.
Yes, gas molecules in air exert pressure on the objects they surround due to their constant motion and collisions with the object's surface. This pressure is what we feel as atmospheric pressure and is responsible for various phenomena like weather patterns and the ability to inflate balloons or tires.
Condensation typically increases air pressure in a closed environment. When water vapor in the air condenses into liquid form, it releases heat, which increases the temperature of the air and causes the air molecules to move faster and exert more pressure on the walls of the container.
Air pressure results from the weight of the air molecules above a given area pressing down. This pressure pushes on surfaces in all directions, exerting a force perpendicular to the surface. The force increases with greater air density and higher elevation.
Depends on how you do that - but most are fatal.
Yes. (see - barometer)

Yes. Atmospheric pressure is the pressure caused by air when it exerts pressure on the surface of earth.
Fluids have a higher density than air and therefore exert more pressure than air.
Water is more dense than air is.
A column of air exerts atmospheric pressure on the air or surface below it. This pressure is caused by the weight of the air above pushing down on the lower air or surface.
If the temperature is increased, the partial pressure of oxygen in a sample of air will also increase. This is because as the temperature rises, the oxygen molecules in the air will have greater kinetic energy and will exert more pressure.
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.
When air is cooled, its molecules lose energy and move closer together, decreasing the air pressure. This is because the lower temperature reduces the average kinetic energy of the molecules, causing them to exert less force on the surrounding area, resulting in lower air pressure.
The air pressure is rising.
There is about 2 ton of air on every square foot of the Earth (less at high altitudes)
