Question

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

Answer 1

Ice at 273°K or 0°C is more effective in cooling than water at the same temperature, due to the fact that for melting each kg of ice latent heat required is of 3.34×10^5 Joules fron the substance and hence cools the substance more effectively.

Answer 2

Because at 0° C (273 K) particles of water have more energy comparing it to water at the same temperature.
