Document Summary
Pressure: air pressure is the force per unit of area exerted on the earth"s surface by the weight of the air above the surface. If the number of air molecules above a surface increases, there are more molecules to exert pressure (weigh down) on a surface and total atmospheric pressure increases. If the number of air molecules above a surface decreases, there are fewer molecules to exert pressure (weigh down) on a surface and total atmospheric pressure decreaases. Both the points above are relative to the atmospheric pressure. If a gas is kept at a constant temperature, pressure and volume are inversely porportionl o o.
