### Educational Content: Thermodynamics in Piston-Cylinder Devices

**Scenario Description:**
A piston-cylinder device contains 1.5 kg of steam at 300°C and 0.4 MPa. The steam is cooled at constant pressure until one-half of the mass condenses.

**Tasks:**

1. **Diagram of the Piston-Cylinder Device:**
- Illustrate the shape of a piston-cylinder, including key components such as the cylinder, piston, and the contained steam.
- Indicate initial conditions (300°C, 0.4 MPa) and place emphasis on the constant pressure process.
- Highlight the phase change with labels marking vapor and liquid phases.

2. **T-v Diagram Explanation:**
- Create a T-v (Temperature vs. specific volume) diagram.
- Plot the initial state of the steam. Note that at 300°C and 0.4 MPa, the steam is in a superheated state.
- Draw a horizontal line indicating the constant pressure cooling process.
- Identify the condensation point where one-half of the steam mass condenses.
- Mark the two-phase region and show the change in specific volume as the steam condenses.

This instructional content offers a practical application of thermodynamic principles, emphasizing understanding phase changes and constant pressure processes in piston-cylinder devices.

3) Find the final temperature.

4) Determine the change in volume.
