Two kg of water exist initially as a vapor and liquid at 90C in a rigid container of volume 2.42

Question:

Two kg of water exist initially as a vapor and liquid at 90°C in a rigid container of volume 2.42 m3.

(a) At what pressure is the system?

(b) What is the quality of the system?

(c) The temperature of the container is raised to 100°C. What is the quality of the system, and what is the pressure? What are ΔH and ΔU at this point relative to the initial state?

(d) As the temperature is increased, at what temperature and pressure does the container contain only saturated vapor? What is ΔH and ΔU at this point relative to the initial state?

(e) Make a qualitative sketch of parts (a) through (d) on a P-V diagram, showing the phase envelope.
