A 15kg sample of water is held at 200°C in a variable-volume container (a piston-cylinder apparatus). An engineer measures its specific volume to be 0.1 m³/kg. The following table shows PVT data for water. a. What is the mass of the liquid phase in kg ? b. What is the volume of the liquid phase in m³ ? c. The volume of the container is increased isothermally until the specific volume is 0.15 m³/kg. What phase(s) is/are present? d. Estimate the approximate pressure of the sample in part (c).
