A piston–cylinder device initially contains 50 L of liquid water at 40°C and 200 kPa. Heat is transferred to the water at constant pressure until the entire liquid is vaporized.

(a) What is the mass of the water?

---

(b) What is the final temperature?

---

(c) Determine the total enthalpy change.

---

(d) Show the process on a diagram with respect to saturation lines.
