All gases work the same way, when your compressing gases, like your example, even CO2 gets really warm. But when they fill CO2 cylinders, they are just transferring a liquid, and a little of that liquid CO2 does turn back into gas as its being filled, and that chills the tank.I work a lot with air conditioning and nitrous. Generally when you compress a gas is gets hotter and when it is released the temp drops, is co2 the opposite of this?
