I gave my students this multiple choice question: Laura adds 50 mL of boiling water to 100 mL of ice water. If the 150 mL of water is then put into a freezer, at what temperature will the water freeze?

Only one answer is correct among these 4 choices:
- 0°C
- 15°C
- 37°C
- 50°C

Could you tell me which one is correct?

0°C
