1. Consider an insulated piston-cylinder arrangement that has 5 Liters of saturated liquid water with given constant pressure of 175 kPa. Using a paddle wheel, water is stirred while a current of 8A flows for 45 minutes through a resistor placed in the water. If 1/2 of the liquid will evaporate during this constant-pressure process and the paddle-wheel has a given work amounts to 400 kJ, determine the voltage of the source. Draw the Pressure versus volume diagram illustrating the process.
