weight
Air pressure decreases as temperature increases, and air pressure increases as temperature decreases. This is because warmer air is less dense and exerts less pressure, while cooler air is denser and exerts more pressure.
air molecules in cold air exert more pressure because they are closer together and collide more often
When air exerts a force, it is called air pressure. Air pressure is the force exerted by the weight of air above a given point.
Atmospheric pressure exists because air has weight. The weight of the air above exerts a force on the air below it, resulting in pressure at the Earth's surface.
Because warm air is less dense than cold air.
Cold air exerts a low pressure. That is why cold air falls and hotter air rises above it.
Air exerts pressure because it contains molecules that are constantly in motion and colliding with surfaces around them. These collisions create a force per unit area, which results in pressure being exerted by the air. This pressure can be measured using devices like barometers or manometers.
Air pressure is generally lower in warm areas because warm air is less dense and therefore exerts less pressure on its surroundings. Cool air is denser and exerts more pressure, so areas with cooler temperatures typically have higher air pressure.
Because the air molecules are packed closer together in cold air.
Cold air has a high pressure because it is heavier than warm air.
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.
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.
