Question

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

Answer 1

Answer:

$\huge \fbox \colorbox{purple}{✍ Answer}$

To achieve the room temperature, the ice at 273 K will absorb latent heat as well as thermal energy. Water at a temperature of 273 K would just absorb heat energy to achieve room temperature. Thus, water at 273 K will absorb less environmental heat energy than ice at 273 K. Therefore ice at 273 K more effective in cooling than water at the same temperature.

Answer 2

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.
