The water was heated up until the temperature is 200C. At this time, a pressure regulating valve installedat the top of the piston was activated which allowed the escape of saturated vapor at the same pressure.The application of heat was continued until the water quality is 100%. Determine the total heattransferred to the system in this experiment.
A piston-cylinder device contains satuated water vapor with a constant pressure. The mass and the pressure are listed in the table below.
