Thanks. I was thinking maybe that in the scenario I presented the thermodynamics might work similar to a heat engine whereby it is heated on one end, then the hot pressurized air released on the other end would turn so cold it is used in cryogenics. Different specific parameters, I guess.

Ok. Begin with a tank with ambient air at ambient temperature and pressure, (we'll assume sea level for the purpose of this question). I paint it black. Then I seal it, (in other words,the released valve is closed). Then I place it in the sun which heats up the air molecules and pressure air...

When pressurized heated air is released does the temperature drop down below ambient temperature, or simply finds temperature equilibrium with ambient air?
