Correct me because I know I'm wrong.

Compressed air has more energy, uncompressed air has less energy. If Compressed air turns into uncompressed air, then the extra energy in released as kinetic energy i.e heat.

But somehow the opposite is true...

All air is compressed. Otherwise, it'd not be "air". It is more or less compressed. Atmosphere pressure will determine the potential energy of air compressed more than the ambient atmosphere pressure.

It has to do with density. When the gas is compressed, you have room temperatures' worth of heat energy evenly distributed throughout the entire volume.

The volume expands without any extra heat energy being introduced, and the room temp's worth of heat energy is like a drop of whiskey in a gallon of water. It gets dispersed, diluted.

It releases it because such little volume can't contain it. There's no more room in there.

Here's another scenario. Temperature is the kinetic energy of air. Yet somehow fast moving air is not hotting than still air. In fact, fast moving air feels cooler than still air.

kinetic energy is within air, not air moving as a whole
