Three chemically non-interacting liquids are mixed in a vessel, having masses m1 = 1 kg, m2 = 10 kg, m3 = 5 kg; temperatures t1 = 6°C, t2 = - 40°C, t3 = 60°C and specific heat capacities c1 = 2 kJ/kg K, c2 = 4 kJ/kg K, c3 = 2 kJ/kg K, respectively. Determine the temperature of the mixture and the amount of heat required to subsequently heat the mixture to t = 6° C.
