At a given temperature, the higher the air density, the higher the air pressure.
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.
Density is related to the flight of hot air balloons because the more density the harder it is to get of the ground.
If you have air in a tight cylinder piston system, when you apply pressure you will see the volume of the air reduced. The amount of mass of air is the same, but now it occupies less volume, the molecules are closer together, its density has increased.
As air pressure pressure decreases with altitude, so does the densite of air.
As air pressure pressure decreases with altitude, so does the densite of air.

Air has both density and pressure.
Pressure affects the density of air by increase of pressure increases the density
Under controlled situations , as the temperature increases the air pressure decreases.:)
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.
Scroll down to related links and look at "Density of air - Wikipedia" and "Atmospheric pressure - Wikipedia". The density of air is the mass per unit volume of Earth's atmosphere. Air density decreases with increasing altitude, as does air pressure. Air pressure (N/m² = Pa) is a column of air pushing on top of you. If you think of a stack of books, then the bottom has the greatest pressure and the top has the least.
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.
For a given volume and pressure, the mass of the air contained in that volume (density) will decrease as the temperature increases.
