Aubrey put two identical bottles of water in the freezer to cool. She put one bottle near the front of the freezer and one near the back. This table shows how the temperature of each
bottle of water changed over 15 minutes.
Bottle of water Initial temperature (°C) Final temperature (°C)
Bottle near the back 23

quickly. What should she do to maximize the rate of thermal energy transfer out of the
bottle of water?
