A well insulated piston-cylinder device with a free floating piston contains 1 kg of a 25% quality saturated misture of water at 150 degree C. A resistance heater with a power rating of 1800 Watts operates for a certain time causing all of the liquid to be vaporized. The piston is now locked into place and the water is further heated until it reaches 200 deg C. Determine a) the initial and final pressure b) the total energy (via electric work) added to the water c) the total boundary work done; and d) the total time for the process.
