During a college prep class last year, my physics teacher said something about the direction of heat. He asked a student, "Which direction does heat go? From hot to cold, or cold to hot?" I'm pretty sure that's what he asked.

I wish I had spoken up, but I didn't. Now I'm stuck on this. Can you explain this "direction"?

direction of flow of heat is from hot to cold conventionally .it is due to the reason that every system in nature tries to attain minimum energy.A hot cup of coffee gets cool after sometime or stated another way "the temperature of surronding rises".Its up to u how do u look at nature.
