Question

Why is ice at 273K were effective in cooling that water at same temperature

Answer 1

ice at 273 K is more effective in cooling than water at the same temperature because in eyes there is less energy as compared to water because in water the particles are constantly moving and in liquid particles move much faster than as compared to solids therefore there is less kinetic energy in eyes as compared to the water

Answer 2

Ice at 273 K will absorb heat energy or latent heat from the medium to overcome the fusion to become water . So ice is more effective in cooling than water at the same temperature .
