You have a rigid tank that contains R-134a at a quality of 0.40 and 200 kPa. Thermal energy is now transferred to the tank from a high temperature source at 35 oC. This energy transfer process contiunes until the tank is at 400 kPa. The initial size of the tank is 0.5 m3. Determine the TOTAL (not specific) entropy change in the source. Give your answer in kJ/K and to FOUR significant digits.
