Higher temperature air is less dense.Less-Dense air has a higher temperature
the higher you are the more the density decreases
Air pressure is caused by the weight of all the air stacked up above you. The higher you go, the less air there is above you, so the pressure is lower.
Heated gas has a lower density than environmental air.
At a given temperature, the higher the air density, the higher the air pressure.
The density of air decreases as altitude increases.
because at higher temperature the air become light i.e. density is lower , so it flows from higher density to lower density area.

Simply put, the higher the altitude, the lower the density of the air molecules.
They stay the same :)

= 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.
greater
Lower temperature air is more dense.
The lower you go into the sea level, the greater the air pressure. The higher you go above the sea level, the lower the air pressure.
