Two amounts of salt water at different temperatures are brought into thermal contact with each other and mixed thoroughly. The first amount of water has mass m1 = 0.352 kg and its initial temperature is T1 = 8.11 °C. The second has a mass of m2 = 0.923 kg and an initial temperature of T2 = 36 °C. Assume that the system is isolated. Let the specific heat of the water at this salinity to be CW = 0.86 kcal / kg / K. a. Find the total change in entropy of the system, in kcal / K.
