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 = 0.302 kg and its initial temperature is T1 = 7.41 °C. The second has a mass of m2 = 0.823 kg and an initial temperature of T2 = 34.5 °C. Assume that the system is isolated. Let the specific heat of the water at this salinity to be CW = 0.91 kcal / kg / K After both amounts of water are mixed and reach thermal equilibrium, what is the total change in the amount of internal energy, in joules, of the system?
