A gas (including air) will expand if the temperature increases. That means the same mass of gas will have a larger volume. Since density is mass / volume, that means the density will decrease.
When air rises, it expands and cools, which causes its density to decrease. Conversely, when air descends, it compresses and warms, which causes its density to increase.
The density of air decreases with an increase in height due to the decrease in pressure and temperature with altitude. As you go higher in the atmosphere, there are fewer air molecules present, leading to lower air density.

As elevation increases, air pressure decreases, leading to lower air density. This decrease in air density at higher elevations can impact various factors such as aerodynamic performance, engine power output, and oxygen availability for living organisms.
Yes, humidity can affect air density. Moist air is less dense than dry air because water vapor molecules are lighter than nitrogen and oxygen molecules. Therefore, higher humidity levels can lead to lower air density.
When air rises, it expands and cools, which causes its density to decrease. Conversely, when air descends, it compresses and warms, which causes its density to increase.
An increase in air density will mean a decrease in the absorption and radiation of energy. An increase of air density causes temperature and pressure to rise.
The density of air decreases with increasing altitude.
Pressure affects the density of air by increase of pressure increases the density
as you increase elevation (height above sea level0the density of the air decreases.
The densities of the noble gases increase with increasing molecular mass. The increase in density is due to the increase in atomic mass. Helium is about one seventh the density of air and can be used in balloons and lighter-than-air craft. Xenon is about five times the density of air.
As you increase in altitude, the density of air molecules decreases. This is because the air pressure decreases with increasing altitude, leading to a lower concentration of air molecules in a given volume of space.

The density of air decreases with increasing altitude because air at high altitudes is under less pressure.
