Does unsaturated air expand or compress?

Unsaturated air typically expands when it rises in the atmosphere due to the decrease in pressure. Conversely, unsaturated air tends to compress when it descends to lower altitudes where the pressure increases.


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.


When the air rises does it increase or 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.


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.


Does rising air expand or contract?

Rising air expands as it moves to higher altitudes where there is lower atmospheric pressure. The expansion of the air causes it to cool, leading to the formation of clouds and potential precipitation.


Is the air in the room saturated or unsaturated?

To determine if the air in the room is saturated or unsaturated, you would need to measure the humidity level. If the humidity level is at 100%, then the air is saturated. If it is below 100%, then the air is unsaturated.


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.


When air rises fom the ground it always compresses and warms?

As air rises, it experiences lower pressure and expands. This expansion causes the air to cool as it rises, rather than compress and warm. As the air cools, moisture may condense to form clouds and precipitation.


What is the function of compressor?

It compresses be it air or freon or whatever.
