Water freezes at 0 Celisus. If a temperature drop is causing a glass of water to freeze, how would a thermometer in the water most likely change as the water freezes?

A. The temperature would keep rising steadily.
B. The temperature would keep falling steadily.
C. The temperature would fall to 0 celisus and stay there until all the water froze.
D. The temperature would not change or would change unpredictably

What do you think? Assume the water is in a freezer well below freezing, say at -23C. Your teacher should have told you that.

is it b

Absolutely not. While freezing, energy is being absorbed to arrange molecules, and it cannot get colder until all the molecules are aligned as a solid matrix. It takes time.

is it c

yes.

thank you

To determine how a thermometer in the water would most likely change as the water freezes, we need to understand the freezing process and its impact on temperature. When water freezes, it goes through a phase change from a liquid to a solid. During this phase change, the temperature remains constant until all the water has solidified.

Based on this information, we can conclude that the correct answer is:

C. The temperature would fall to 0 degrees Celsius and stay there until all the water froze.

As the temperature drops due to the cooling effect, the thermometer would indicate a gradual decrease until it reaches 0 degrees Celsius. Once it reaches 0 degrees Celsius, the temperature observed by the thermometer would remain constant until the entire glass of water has frozen.

Therefore, option C is the most accurate representation of how the thermometer would change as the water freezes.
