Question

Why is ice at 273 K more effective in cooling than water at the same temperature?

Answer 1

1. The ice at 273 K will absorb thermal energy as well as latent heat to reach room temperature.
2. Water would simply absorb heat energy to reach room temperature at a temperature of 273 K.
3. Water will therefore absorb less heat energy from the surroundings at 273 K than ice will.
4. Ice is therefore more efficient at cooling at 273 K than water is at the same temperature.
