Don’t know if it happens to other cans as well but why do spray paint cans feel cold when we touch after shaking them?
In: Chemistry
PV=nRT
Basically, in physics the pressure and volume have to balance out against the temperature. If you lower the (P)ressure (in this case without changing (V)olume), then you have a lower (T)emperature on the other side to balance out. (N and R are constants if I remember right.) It’s how refrigeration works too. You pump the coolant around and change the pressure to make things hotter or colder. It’s the same reason canned air gets colder too
