Why is ice

Answer :

273 K or 0°C is the melting point of ice.Now, ice at 273 K is more effective in cooling a substance than water at the same temperature because in order to overcome the fusion to become water, ice at 273 K will absorb heat energy from the surroundings known as latent heat of fusion. Hence, the cooling effect of ice will be more than water at the same temperature because water does not absorb this extra heat from the medium.

The latent heat of melting of ice is 334 Joules per kilogram
