Question

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

Answer 1

Ice at 273 K will absorb heat energy or latent heat from the medium to overcome the fusion to become water. Hence the cooling effect of ice is more than the water at same temperature because water does not absorb this extra heat from the medium.

Hope it helps you

Answer 2

Because Ice absorb more heat than the water from hot body due to its Latent heat of fusion
