Assuming the conditions for an ideal gas: PV=nRT (an "ideal" gas)
V =nR/P * T --> V=volume, T=temperature,
D=M/V --> D=density, M=mass, V=Volume
Therefore
D =M/(nR/P *T) -->Sub in for V
D=MP/(nRT)
If you assume constant MP/nR then
D = k/T , k=MP/nR, D=density and T= temperature
Higher temperature air is less dense.Less-Dense air has a higher temperature
Both pressure and volume of any gas are directly, linearely proportional to temperature in Kelvin, that is degree Celsius + 273.13. Density is not directly related to temperature, it is related to mass and volume.
= What is low air density? = well, high or low are relative concepts. Normally the standard air density of the air is defined as the density of the air at 15ºC and at sea level pressure (standard conditions), what give a value of 1,225kg/m3. This way, we can talk about high or low air density related to the standard value. Air density depends on temperature and pressure. The colder the temperature the higher the density is, and the higher the height in the atmosphere the lower the density becomes. In the Everest peak, e.g., air density can be lower than 0,5. Meanwhile in the Antarctica (at sea level) the density could reach values higher than 1,5.
Sorry, the atmospheric pressure has really nothing to do with the speed of sound at 0c, but he temperature is very important Scroll down to related links and read the short article "Speed of sound - temperature matters, not air pressure". The air pressure and the air density are proportional to each other at the same temperature.
The temperature of a region is affected by the height of the place, how slanted the place is, air pressure and air density.

For a given volume and pressure, the mass of the air contained in that volume (density) will decrease as the temperature increases.
Lower temperature air is more dense.

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.
