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