If you put a piece of very hot metal in cold water the heat in the metal will transfer to the water until both are the same temperature. So the system water-metal still has the same initial energy.
So my question is how does the piece of metal cool if it is put on a perfect vacuum.
Is it electromagnetic waves that the metal emits or something like that?
