silkworm Posted December 17, 2005 Share Posted December 17, 2005 I'm sorry to bother the forum with this but a question came to my mind in a part of physics I have not studied thoroughly and the semester is over so I can't bother any physics professors right now and I've come to an assumption and I was curious if it was valid. Say you have a solid body in space that is hot, it's excited molecularly. And it cools. Did the heat escape by emission of electromagnetic waves?
