A student takes the temperature of a bottle of liquid water in the tub filled with ice. The student then places the bottle of liquid water into the tub of ice. After 15 minutes, which of the following best describes what happens to the temperature of each?

After placing the bottle of liquid water into the tub of ice, the temperature of both the bottle and the tub of ice will start to equilibrate. As heat flows from the water in the bottle to the ice in the tub, the temperature of the water will decrease, and the temperature of the ice will increase slightly.

Therefore, after 15 minutes, the temperature of the water in the bottle will likely decrease, while the temperature of the ice in the tub will slightly increase.
