As shown in the figure below, a system consists of a copper tank whose mass is 12.5 kg, 4 kg of liquid water, and an electrical resistor of negligible mass. The system is insulated on its outer surface. Initially, the temperature of the copper is 27°C and the temperature of the water is 50°C. The electrical resistor transfers 200 kJ of energy to the system. Eventually the system comes to equilibrium. Determine final equilibrium temperature in °C.
