An insulated piston-cylinder device initially contains 1.4-kg saturated liquid water at 200°C. Now an electric resistor placed in the tank is turned on for 20 min until the volume quadruples. Determine (a) the volume of the tank, (b) the final temperature, and (c) the electrical power rating of the resistor.
