A chunk of ice of mass m1 = 100 g at a temperature t1 = 0 °C was placed in a calorimeter in which water of mass m2 = 100 g was at a temperature t2. Assuming the heat capacity of the calorimeter to be negligible, find the entropy increment of the system by the moment the thermal equilibrium is reached. Consider two cases: (a) t2 =60 °C; (b) t2 = 94 °C. |
