they don't typically have anything to do with each other. but the hotter the air temperature the more the molecules in the air move causing it to press harder on the surfaces around it making hotter air have a lower air pressure but it is opposite with colder air. =D
Air has both density and pressure.
Pressure affects the density of air by increase of pressure increases the density
Altitude has a large affect on the air pressure and air density. Air density reduces with altitude and air pressure reduces with altitude as well.
At a given temperature, the higher the air density, the higher the air pressure.
density decreases as air pressure increases
Air pressure decreases as altitude increases. As air pressure decreases, so does density.
As air pressure pressure decreases with altitude, so does the densite of air.
When altitude rises, the air pressure and density both decrease. When temperature rises that means that more air is pushing down on it. So this means that the air pressure and density rise when temperature rises.

density
Air pressure varies because of the differences in air's density.
as the altitude increase, the effect of gravity become more insignificant on air and the air become more disperse or thinner hence it does affect the air pressure and density by decreasing both air pressure and density of the air.
