3-51 A piston-cylinder device contains 0.005 m of liquid water and 0.9 m³ of water vapor in equilibrium at 600 kPa. Heat is transferred at constant pressure until the temperature

reaches 200°C. (a) What is the initial temperature of the water? (b) Determine the total mass of the water. (c) Calculate the final volume. (d) Show the process on a P-V diagram with respect to saturation lines.
