Question

1. Which requires more heat: 1 g ice at 0℃ or 1 g water at 0℃ to raise its temperature to 10℃?
2. Explain your answer in part (a).

Answer 1

1. 1 g ice at 0°C requires more heat because ice would require additional heat energy equal to the latent heat of melting.
2. 1 g ice at 0°C first absorbs 336 J heat to convert into 1 g water at 0°C.
