How is temperature related to high and low pressure air?
Cool air near the surface forms high-pressure areas, warm air forms low-pressure areas. Cool air has air particles that are at a lower temperature, hence have less kinetic energy and are closer together to each other, hence cool air is denser and so has a higher pressure.Click to see full answer.

Cool air near the surface forms high-pressure areas, warm air forms low-pressure areas. Cool air has air particles that are at a lower temperature, hence have less kinetic energy and are closer together to each other, hence cool air is denser and so has a higher pressure.Click to see full answer. Herein, what is the relationship between temperature and air pressure?The relationship between the two is that air temperature changes the air pressure. For example, as the air warms up the molecules in the air become more active and they use up more individual space even though there is the same number of molecules. This causes an increase in the air pressure.Similarly, how does low pressure affect temperature? As the number of molecules increases, they exert more pressure on a surface and the total atmospheric pressure increases. By contrast, if the number of molecules decreases, so too does the air pressure. One may also ask, why does the air pressure rise with fall in temperature? Warm air causes air pressure to rise. When air molecules collide, they exert force on each other. When gas molecules are heated, the molecules move more quickly, and the increased velocity causes more collisions. Temperature affects air pressure at different altitudes due to a disparity in air density.How does pressure change with temperature?The pressure in PV=nRT is the force exerted by the gas on the walls of the container. As the temperature increases, the particles move faster, and therefore have greater speeds, so greater momentum and therefore greater force when they collide with the walls, so the pressure increases.
