1285. If I have two glass containers with equal amounts of water both at the same temperature (say 80° F), and put one in the refrigerator and one in the freezer, which container will cool to 40° F first? Because the freezer is colder, I would guess the freezer. — JL, Eagan, MN
You're right. The greater the temperature difference between two objects, the faster heat flows between them. This effect is useful whenever you forget to chill drinks for a party. Just don't leave a glass bottle in the freezer too long; if the water inside freezes, it may expand enough to break the bottle.
