Homework Statement

I need to find out which freezes faster--hot or cold water--without doing a lab. Just by thinking and considering laws and theories and properties we have learned about.

The Attempt at a Solution

It seems like it would be cold water since the hot water would have to catch up... But correct me if I am wrong.

I didn't think I could put it in homework because it doesn't involve equations, but I got a warning so I did the best I could to repost and do it as the rules say.
