A rigid (closed) tank contains 16 kg of saturated water at 90 °C. If all of this water is in the saturated form, answer the following questions:

• a) Determine the steam quality in the rigid tank.
• b) Is the described system correspond to a pure substance? Explain.
• c) Find the value of the pressure in the tank.
• d) Calculate the volume (in m³) occupied by the gas phase and that occupied by the liquid phase (in m³) if 15% of the mass of liquid water passed into the vapor phase.
• e) Deduce the total volume (m³) of the tank.
• f) On a T-v diagram (assume constant pressure), draw the behavior of temperature with respect to specific volume showing all possible states involved in the passage of compressed liquid water into superheated vapor.
• g) Will the gas phase occupy a smaller volume if the volume occupied by the liquid phase decreases? Explain your answer (without calculation).
• h) If liquid water is at an elevation of 9800 m above sea level, explain how boiling temperature varies with decreasing elevation.
