True:
- Its temperature will rise until reaching 0° C.
- Its temperature will remain at 0° C until all the ice melts.
Explanation: heating raises the ice’s temperature from −10°C up to 0°C (using sensible heat). At 0°C further input goes into the latent heat of fusion, so the temperature stays at 0°C while the phase change occurs. After all ice is melted, additional heat raises the water temperature above 0°C. Statements 1 and 3 are false for the reasons above.
