Question
- Which requires more heat: 1 g ice at 0℃ or 1 g water at 0℃ to raise its temperature to 10℃?
- Explain your answer in part (a).
Solution
- 1 g ice at 0°C requires more heat because ice would require additional heat energy equal to the latent heat of melting.
- 1 g ice at 0°C first absorbs 336 J heat to convert into 1 g water at 0°C.
