The correct response is:
The temperature of the ice increases, while the temperature of the water decreases.
Here's the reasoning: When the bottle of warmer water is placed into the tub of ice, heat will transfer from the warmer water to the colder ice. This will result in the ice gaining heat and increasing in temperature, while the water loses heat and decreases in temperature. Therefore, the ice in the tub starts at a lower temperature and ends at a higher temperature, while the water starts at a higher temperature and ends at a lower temperature.
