Example 20-6 Entropy change in melting. A 1.00-kg piece of ice at 0oC melts very slowly to water at 0oC. Assume the ice in contact with a heat reservoir whose temperature is only infinitesimally greater than 0oC Determine the entropy change of (a) the ice cube and(b)the heat reservoirEntropy change in melting.
