If it takes 500 joules of heat to melt an ice cube, how much heat would be given off to re-freeze the water?

What is your train of thought? Do you have any idea what this kind of phase change, and the heat difference associated with it, is called?

It either takes more, less, or exactly the same amount of energy. Yeah, I know, that sounds dumb of me to mention.
But if it took more or less, wouldn't that be

useful? As a free source of energy? Ever hear of any of those, in real life?

Hey, I'm not judging. I just like to shoot straight. I'm a man of science.
