Does unsaturated air expand or compress?
Unsaturated air expands. It cools quickly and expands as it rises. As it begins to rise, its relative humidity increases.
Does temperature affect the amount of air in a football?
Yes, the football will appear "flat" as the air compresses in cold weather. Air expands as it warms, and so air in a football, tire, etc. will do the same.
Why does ascending saturated air cool more slowly than ascending unsaturated air?
Saturated air contains relaitvely higher amount of water molecules. Thus it requires much time to cool. Whereas in case of unsaturated air, the number of water molecules are less. So, it's much obvious that lesser amount of water molecules require less time to cool.
As air is heated its relative humidity?
Air expands when it is heated.
Does rising air expand or contract?
Rising air cools and compresses adiabatically.
Does unsaturated air expand or compress?
Unsaturated air expands. It cools quickly and expands as it rises. As it begins to rise, its relative humidity increases.
Does a divers bouyancy change with depth?
Absolutely - air compresses at depth, and because wetsuits are made up of air cells, they compress and lose buoyancy along with the air in the BCD, so divers have to add air while descending. Also, as you breathe air, the tank gets about 6 pounds lighter during the dive, so you need to release air. Finally, as air expands while ascending, you need to let air out.

What happens to the volume of air in your lungs when you ascend to the surface of the ocean?
The air in your lungs expands in volume as you get closer to the surface of any water you swim in. This is because the air was compressed when deeper due to the pressure of the water around you. This is why when scuba divers always exhale while ascending to avoid rupturing their lungs as the air expands.
Warm air rises at the equator and cold air sinks at the poles creating?
Warm air rises at the equator and cold air sinks at the poles. Warm air expands and cool air contracts and compresses.
Is the air in the room saturated or unsaturated?
If it is humid it is saturated. If it is dry it is unsaturated.
As air is heated its relative humidity?
Air expands when it is heated.
What is function of compressor?
It compresses be it air or freon or whatever.
What is the purpose of piston?
It compresses the air in a engine or compressor.
What does the compressor in an air conditioner do?
It compresses the freon gas.
What is the purpose of a piston?
It compresses the air in a engine or compressor.
