How is temperature related to air pressure?

Question

Need for Homework NOW~!!!!!!!!!!!!!!

Answer 1

When a particular place is heated ,the atmosphere above that place is heated from below and the air becomes less dense and starts raising due to bouyancy.Due to this convection process, the raising air spreads above a particular height and the rarified air over that place causes less pressure. So when temperature raises pressure comes down.

Answer 2

Temperature and pressure are related through the equation of state which says PV = R*T where P is the pressure, V is the volume, R* is the universal gas constant, and T is the temperature. So if the volume of air is held constant, the pressure is likely to go up if the temperature goes up.

Answer 3

High temperature causes greater ait pressure. This occurs because high temperatures mean higher level of energy for the individual gas atoms, which causes them to move faster. Faster movement causes the gas atoms to collide with the container more often, and thus create greater pressure.
