Water at 273 K is less effective in cooling than ice at the same temperature. It is because :
water is difficult to handle
water at 273 K has less energy than ice at the same temperature
water at 273 K has more energy than ice at the same temperature
water is not a cooling agent
Answer is Right!
Answer is Wrong!

Therefore, water at 0°C possesses this latent heat energy in addition to the energy contained in ice at 0°C.
When ice is used for cooling, it absorbs heat to melt, providing significant cooling due to the latent heat. The resulting water then absorbs further heat as its temperature rises. When water at 0°C is used for cooling, it only absorbs heat as its temperature rises, which provides less cooling capacity compared to the phase change process of ice.
