Answer 1

hey dear here is ur ans...
ice at 273 k more effective in cooling than water at the same temperature because for melting, each kilogram of ice takes 3.34*10to the power 5 joules of latent heat from that substance and hence cools the substance more effectively. On the other hand,water at the same temperature of 273k cannot take away any such latent heat from the substance and hence doesn't cool it more effectively.

i hope it will help u... nd mark my ans as brainliest...

Answer 2

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