Let’s say you put a running refrigerator inside a closet, close the closet, open the refrigerator door, why does the closet warm up?
I know it has to do with thermodynamics, and how fast the refrigerator can cool the air versus how hot is the surrounding air. No equations necessary, just why you think it’s happening. Thanks!
Lots of good explanations, Thanks everyone!
Lee_: Yes It’s Mandela with Laila Ali 🙂
Rob S: No I did not try it 🙂

A refrigerator is a heat pump. By using some pretty nifty physics with fluid expansion it draws heat from the inside even though it’s already cold and releases it to the outside environment.
If you open the refrigerator door inside the closet then the system will eventually reach an equilibrium point between itself. The heat in the closet will be generated solely from the fluid pump on the back of the fridge at this point (which will be pretty hot from running nonstop!)
