At 0°C 20g of ice are added to 50g of water at 30°C in a vessel that has a water equivalent of 20g. Calculate the entropy changes in the systems and in the surroundings. The heat of fusion of ice at 0°C is 6.02 kJ mol-1, and the specific heat capacities of water and ice may be taken as constant at 4.184 and 2.094 JK-1g-1, respectively, and independent of temperature.
