An insulated piston-cylinder device contains 4 L of saturated liquid water at a constant pressure of 200 kPa. Water is stirred by a paddle wheel while a current of 8A flows for 50 min through a resistor placed in the water. If one-half of the liquid is evaporated during this constant-pressure process and the paddle-wheel work amounts to 300 kJ, determine the voltage of the source. Also, show the process on a P-v diagram with respect to the saturation lines.
