I gave my students this multiple choice question: A container is filled with 100 mL of water and placed in a freezer. The water in the container freezes at 0°C. A second container filled with 90 mL of water is placed in a second freezer. At what temperature does this second container of water freeze?

Only one answer is correct among these 4 choices:
- -10°C
- -1°C
- 0°C
- 10°C

Could you tell me which one is correct?

0°C
