One kilogram of ice at 0∘C melts reversibly at the same temperature to form water at 0∘C. The latent heat of fusion of ice is Lf=3.34×105Jkg−1.
a. (i) Calculate the amount of heat absorbed during the melting.
b. (ii) Determine the change in entropy of the ice–water system.
c. (iii) If the surroundings are also at 0∘C, compute the entropy change of the surroundings.
d. (iv) Hence find the total entropy change of the universe for this melting process.
