1.	Why is ice at 273K more effective in cooling than water at the same tempreature?
Answer» The temperature of 273K is equal to 0℃ and it is the melting point of ice ( to form water ) at the same temperature . Another point to be noted is thet the latent heat of melting of ice ( or fusion of ice ) is 3.34×10×10 ×10×10×10joules pee kg . Now ice at 273K 8s more effective in cooling a substance than water at the sane temperature of 273K because melting ,each kg of ice takes 3.34×10×10×10×10×10joules of its latent heat from the substance and hence cools the substance more effectively. On the other hand water at the same temperature of 273K cannot take away any such latent heat from the substance and hence does not cool it more effectively .
