Question

how will you explain the following observations? Ice at 273 K is more effective in cooling than water at 273 K.

Answer 1

ice at 273 k is more effective in cooling than water at 273 k because water have some heat dissolved in it in the form of latent heat of fusion which is not present in ice at same temperature

Answer 2

hey .
0°C = 273k
At temperature 0°C you can find both form of water . Liquid and solid too .
THE TEMPERATURE OF ICE AT 0°C is more effective than the water at 0°C because of its solid form .
Hope it helps.
