An insulated piston-cylinder device contains 3 liters of saturated liquid water at a pressure of 150 kPa. A current of 10 Amps flows for 45 minutes through an electrical resistor that is placed in the water, while the water is stirred by a paddle-wheel (shaft work) that is adding 400 kJ of mechanical work to the system during that period. If one-half of the liquid water mass that is inside the cylinder is evaporated during this constant pressure process, determine the voltage of the electric source that is connected to the electrical resistor. Plot the T- v or the P – v diagram for the process.
