Question

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

Answer 1

Answer:

Solution : Cooling takes place when heat is removed from a system. ... So, at same temperature of 273 K, large amount of heat will be removed by ice from the surroundings than in case of water. Hence, ice at 273 K is more effective in cooling than water at the same temperature.

Answer 2

Answer:

when ice starts to melt ,it absorbs heat from it's surrounding and hence the surrounding become cool while when the cold water at the same temperature is already in liquid form ,it too absorbs heat from the surroundings but it takes time and is not able to cool as much as the ice
