38) an insulated piston-cylinder device contains 5 l of saturated liquid water at a constant pressure of 175 kpa. Water is stirred by a paddle wheel while a current of 8 a flows for 45 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 400 kj, determine the voltage of the source.
