BlakeIf 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.

What happens in an empty tank when it is filled with air?
When an empty tank is filled with air, the air molecules move into the tank and exert pressure on the walls of the tank. This increases the air pressure inside the tank and causes the tank to become pressurized.
Why does the atmosphere exert pressure?
The atmosphere exerts pressure because of the weight of the air above pushing down on the air below. This pressure is caused by the force of gravity acting on the mass of the air molecules in the atmosphere.
What pressure does cold air exert?
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.
Does gas molecules in air exert pressure on the objects they surround?
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.
How do gas particles exert pressure on their container?
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.
