Half-Dead

so what happens to the heat that isn't transferred back into the atmosphere? Does that cease to exist? or stay in the warmed body? Sorry to be a questioning pain... i'm trying to get my head around this haha! I'm probably missing a key piece of the puzzle but If the energy that doesn't go in the atmosphere just disappears then surely energy can indeed be destroyed. I think i'm getting there lol

I think you're talking to the dead half today haha! Thanks for your answer. It answers my question since it provides me with ideas that hadn't entered my head. I never would have thought about the tiny movement of walls/doors etc. I assume the heat energy created from the moving windows/walls etc just goes into the atmosphere and then exists... am i right? Thanks Thanks. This indeed does answer my question.

Hi guys, I have this question about energy that I sometimes think about and I thought a good way to get some sort of answer is to visit a forum dedicated to science so here I am. My question might sound a little daft so here it is. I'm probably alone in thinking this haha! What happens to sound energy? They say energy can't be destroyed and can only change from 1 form to another.... like a light bulb changes electrical energy into heat etc. However, what happens if we listen to music? To my way of thinking our stereo system converts electrical energy to sound (and a bit of heat) but where does the sound energy go after the song is finished? does it just exist somewhere but in what form? if it can't just die or be destroyed then it has to exist somewhere. Thanks
