A piston-cylinder device contains 0.1 m3 of liquid water and 0.9 m3 of water vapor in equilibrium at 800 kPa. Heat is transferred at constant pressure until the temperature reaches 350°C.
(a) what is the initial temperature of the water,
(b) determine the total mass of the water,
(c) calculate the final volume, and
(d) show the process on a P-v diagram with respect to saturation lines.
