Question

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

Answer 1

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.
