Web4. An insulated piston-cylinder device contains 4 L of saturated liquid refrigerant-134a (R-134a) at a constant pressure of 200 kPa. An electric resistance heater inside the cylinder is now turned on, and 1185 kJ of energy is transferred to the steam. Determine the entropy change of the water during this process (20 P). WebThe system is the R134a contained in the tank. Since the tank is rigid and closed, the system volume and mass are constant. Thus, the specific volume of the system also remains constant (recall that v = V/m), i.e., v 2 = v 1. We’re told that the system is a saturated vapor at 20 °C. Using the SLVM-temperature table, at T 2 = 20 °C, p
