An insulated piston cylinder device contains 5 L of saturated liquid water at a constant pressure of 150 kPa. An electric resistance heater inside the cylinder is now turned on and 2200 kJ of energy is transferred to the steam as shown in the Figure 2.1. Determine the entropy change of the water during this process. 2200 kJ Saturated liquid insulated www Figure 2.1 Piston
