1. A frictionless piston-cylinder device contains 8 kg of superheated water vapor at 300 kPa and 250 °C. Steam is now cooled at constant pressure until 80 percent of it, by mass, condenses. Determine the work done during the process. Also, sketch the process on a P-v diagram with respect to the saturation lines.
