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.
Cold air exerts a low pressure. That is why cold air falls and hotter air rises above it.
The force that air exerts on your body is called air pressure. This force is a result of the weight of the air above you pressing down on your body.
The force that air exerts on all objects is called air pressure. This force is due to the collisions of air molecules with the surface of an object.
The force that air exerts on the surface of the Earth is called atmospheric pressure. It is caused by the weight of the air above pushing down on the surface.
Yes! The heated air molecules always wants to fly upwards because of being lite. We can take the example of a ballon filled with air. When ballon is heated the pressure increases and ballon brusts. This proves that hot air exerts pressure.
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.
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.

Cold air exerts a low pressure. That is why cold air falls and hotter air rises above it.
air molecules in cold air exert more pressure because they are closer together and collide more often
A mean air pressure is 760 mmHg This means that atmospheric air pressure will support a column of mercury (Hg) to the height on 760 millimetres. NB If water was used the column would be approximately 34 feet ( 10.2 metres). In 'old money' approximately 14 lbs per square inch .

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.
The force that air exerts on your body is called air pressure. This force is a result of the weight of the air above you pressing down on your body.
Yes. Atmospheric pressure is the pressure caused by air when it exerts pressure on the surface of earth.
