Question

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

Answer 1

Answer:

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. (273K=0C)

Answer 2

$\huge\sf{\pink{\underline{\underline {♡Answer}}}}$

Ice at 273K is more effective in cooling than water at the same temperature as cie takes latent heat from the substances for melting and hence cools the substances more effectively than water at the same temperature.
