why is ice at 273 K more effective in cooling than water at the same temprature
Answers
Ice at 273 K is more effective in cooling than water at the same temperature as ice takes latent heat from the substances for melting and hence cools the substances more effectively than water at the same temperature.
Cooling takes place when heat is removed from a system, in case of ice at 273 K, it will take latent heat from the medium to convert itself into water at 273 K there will be a change in physical state, whereas in case of water at 273 K there will be no change in state. Hence lesser energy will be taken from the medium.
Ice is more effective in cooling than water at the same temperature because ice can absorb latent heat as well as the heat energy in order to attain room temperature.
Water at 0° C can absorb heat energy only to attain the room temperature.
