Question

why is ice at 273k more effective in cooling than water at the same temprature ?​

Answer 1

Explanation:

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 works out

Answer 2

Answer:

becoz ice at 273 degrees Kelvin means it's a absolute temperature that in celsius scale is zero degrees but this temperature to the water is doesn't effective cooling more than ice ...since becoz ice have five hundred forty cal. in latent heat of vapourization
