A PVT cell containing pure water (H₂O) shows two equilibrium phases of vapor and
liquid at 336.75°C. Answer the questions below by using Appendix A.III of Sandler, "steam table."
What is the pressure (MPa) of the PVT cell?
The visual window of the PVT cell shows 70 cm³ of vapor and 3 cm³ of liquid at
What is the mass of water (a total of liquid water and vapor water) in the PVT cell?
Since the water in the PVT cell shows two equilibrium phases at the temperature
(and the corresponding pressure you answered in part a), it has no thermodynamic freedom
(F = 0). When an additional heat is given to the system while keeping the temperature at
336.75°C and the pressure (that you answered in part a), the volume increases from 73 cm³ to
80 cm³. Note that the system is closed; hence, the total mass of water remains the same as
Part b. What is the mass of liquid water, and what is the mass of vapor water?
