I believe compressed air should be colder. Like when you have an air duster can. Or even a car’s turbocharger which compressed air and cools it right? But also, when there is pressure on air parcels doesnt that pressure increase its heat? At the bottom of a valley, the atmospheric pressure is higher so the air that falls to the bottom of the valley is more compressed and hot. It seems to me like compressed air is both hot and cold then? Could someone explain please? 😅
In: Physics
The act of compression inherently will heat the gas involved However, objects tend towards thermal equilibrium with each other, so the warm compressed air will gradually cool to the ambient pressure without losing much pressure.
Similarly, the act of expansion will inherently cool the gas.

The turbocharger compresses and heats the air; you typically install an intercooler immediately after the turbocharger to remove heat from the compressed air before it goes into the engine.
