A Rigid tank is filled with refrigerant R-134a at 310 K. An electric current of 0.2 Amps over 220 Volts is passed through the refrigerant for 3 minutes. The tank is not very well insulated. After many hours, the temperature is measured to be 310 K again. How much heat (if any) the refrigerant lost?
