 June 20th, 2016, 02:40 PM #2 Math Team   Joined: Jan 2015 From: Alabama Posts: 3,194 Thanks: 871 Another totally random question? This goes back to the "gas law": PV= nRT where "P" is the gas pressure, "V" is the volume, n is the number of molecules, "R" is the "gas constant" and "T" is the temperature. After running the gas through in the back of the refrigerator or freezer, so that heat is radiated to the outside, we suddenly drop the pressure while keeping "V", "n", and "R" the same. "T", the temperature must also drop. We then run it through pipes along the interior to pick up heat from the interior. Thanks from MMath
