water chemistry problem: hot water freezes faster than cool water!?
Calculate the energy required by a refridgerator (positive answer) in KJ per mole to completely freeze hot water starting at 82. C, and the energy required to completely freeze the same volume of cool water starting at 22. C.
I am slightly too stupid to understand what you just said, let alone calculate anything, but someone recently told me to fill and ice cube tray with hot water because it would freeze quicker. I could not for the life of me figure out why that would be the case, but I did it anyway.
I have no idea if it actually froze quicker in the end.
Does this help in any way? No, probably not. Sorry.
