4. A rigid tank has a volume of 0.01 m³. It initially contains saturated water at a temperature of 200 °C and a quality of 0.4. The top of the tank contains a pressure regulating valve which maintains the vapor at constant pressure. This system undergoes a process where it is heated until all the liquid vaporizes. How much heat in (kJ) is required? You may assume there is no pressure drop in the exit line.

**Problem Statement:** A rigid tank has a volume of 0.01 m³. It initially contains saturated water at a temperature of 200 °C and a quality of 0.4. The top of the tank contains a pressure regulating valve which maintains the vapor at constant pressure. This system undergoes a process where it is heated until all the liquid vaporizes. How much heat in (kJ) is required? You may assume there is no pressure drop in the exit line. **Diagram Explanation:** The diagram shows a rigid tank with the following annotations: - \( T_1 = 200 \, ^\circ\text{C} \) indicates the temperature of the water inside the tank. - \( x_1 = 0.4 \) represents the quality of the saturated water, signifying the mass fraction of the vapor phase. - \( V = 0.01 \, \text{m}^3 \) is the volume of the tank. - A valve is depicted on top of the tank, with an arrow and label indicating that it maintains constant pressure in the system.
