re: #125 klys (maker of Silmarils)
Actually that one is just the drop in pressure inside the can while the volume remains the same. P1/T1 = P2/T2, so if P2 goes down, so must T2.
SCIENCE.
Why I’m not a scientist. I just assumed, since tetrafluoroethane is used as a refrigerant, it was the reason the can got cold as I used it.
