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.

How does the density of the atmosphere change as altitude increases?
Answer 1 - Air Density varies with AltitudeIf all other factors remain the same, then air density will decrease as altitude increases. Answer 2 - Another OpinionAs the altitude increase, the density decrease so the air velocity increase so the air pressure decrease and as a result we got a large amount of air mass flow rate
What happens to the pressure as the density of air decreses?
As air density decreases, the pressure it exerts decreases, but the pressure exerted on it increases.Remember the equation:PV=nRTAnd since n=mass/molar mass,P=nRT/D, density and pressure exerted ON the system have an inverse relationship--as one increases, the other decreases
Does Air pressure increases as elevation increases?
No. It is a negative correlation which means, as the elevation increases the air pressure decreases.
What do air density and air pressure have in common?
At a given temperature, the higher the air density, the higher the air pressure.
What is air density?
Air density is the mass of air per unit volume, which changes by temperature, humidity, and elevation. Changes in air density will change its pressure. At mean sea level and 20°C, air has a density of approximately 1.2 kg/m3.
What happens to air pressure when density decreases?
density decreases as air pressure increases
How does the density of the air affect pressure?
Pressure affects the density of air by increase of pressure increases the density
When altitude increases does air density?
The density of the atmosphere decreases with altitude.
How does altitude affect density and pressure?
Air pressure decreases as altitude increases. As air pressure decreases, so does density.
Why does temperature affect the air pressure?
Air temperature and air pressure are inversely proportional. As temperature increases, air pressure decreases. This is best demonstrated in an enclosed vessel.
How does altitude affect density and air pressure?
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.
How does altitude affect the density and pressure of air?
Altitude affects density and pressure by decreasing when it increases.
If the density of air decreases what happens to the pressure?
increases
What happens to air pressure as the altitude of the layers of th e atmosphere increase?
The temperature decreases
How does the density of air change from lower to higher in altitudes?
The density of air decreases as altitude increases.
How does air pressure change as you move up in the atmosphere?
the air pressure increases
How does air pressure change as you move up the atmosphere?
the air pressure increases
