When `1 kg` of ice at `0^(@)C` melts to water at `0^(@)C`, the resulting change in its entropy, taking latent heat of ice to be `80 cal//g` is

When 1 kg of ice at 0^@ C melts to water at 0^@ C, the resulting change in its entropy, taking latent heat of ice to be 80 "cal/".^@C is ____

When 1 g of ice at 0^(@)C melts to form 1 g of water at 0^(@)C then, is the latent heat absorbed by the ice or given out by it?

50 g of ice at 0^@C is mixed with 50 g of water at 80^@C . The final temperature of the mixture is (latent heat of fusion of ice =80 cal //g , s_(w) = 1 cal //g ^@C)

50 g of ice at 0^@C is mixed with 50 g of water at 80^@C . The final temperature of the mixture is (latent heat of fusion of ice =80 cal //g , s_(w) = 1 cal //g ^@C)

1 g ice at 0^@ C melts to form 1 g water at 0^@ C. State whether the latent heat is absorbed or given out by ice.
