Why is ice at 273 K more effective in cooling than water at the same temperature?
When a substance is converted from its solid phase to liquid phase the heat required to convert it is known as the heat of fusion.When the substance in the liquid phase is converted to a gaseous phase the heat required to convert is known as the latent heat of vaporization.Heat absorbed by ice is more than water at 273k from the substance to overcome the latent heat of fusion and convert it into a liquid state. A more cooling effect is provided by the ice because of the greater absorption of heat than water. Final Answer Ice absorbs more heat than water at 273k from the substance to overcome the latent heat of fusion and convert it into a liquid state. Thus due to the more absorption of heat, it provides a more cooling effect. Water does not absorb any extra heat from the substance less cooling effect is observed in the case of water.
