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.

Does the air increase or decrease towards the surface with a high pressure?
Air density and pressure increase nearer the surface
Why does density of air decrease with increase in height?
The density of air decreases with increasing altitude because air at high altitudes is under less pressure.
Does humidity affect air density?
Yes humidity effects the density of air in a way when humidity increases the air density decreases . the reason behind this phenomena is when the amount water vapor increases the major air content i.e O2 and N2 decreases per volume and since we are talking about air density we say density of air is decreased.
Air temperature increases density?
an increase in air temperature causes expansion of gas therefore a decrease in density. colder air is denser hence valley bottoms are often colder
As the air on the surface of earth warms does its density increase or decrease?
As air gets warmer, it expands and becomes less dense.
What effect does air density have on the absorption and radiation of energy?
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.
Does the density of the air increase as altitude increases?
The density of air decreases with increasing altitude.
What happens to the density of air molecules as you increase in altitude?
the density decreases
How does the density of the air affect pressure?
Pressure affects the density of air by increase of pressure increases the density
Air density decreases with elevation increase. Is there an equation to make this calulation?
as you increase elevation (height above sea level0the density of the air decreases.
What is the trend in density in noble gases?
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.
What is the trend in density as you go down the group of noble gases?
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.

Why does density of air decrease with increase in height?
The density of air decreases with increasing altitude because air at high altitudes is under less pressure.
How does the density of air increase or decrease?
By Removing or addng heat
Does cold air increase or decrease water density?
decrease
