Work and Heat Transfer

It is generally related to thermal engineering which tells about the use, creation, conversion and transfer of heat energy between the systems. It is also considered that to transfer heat from one source to another, transfer of masses is also required. There are various mechanisms by which, transfer of heat takes place i.e. thermal conduction, convection, radiation or by change of phase. All these mechanisms have their own specific features which sometimes occur simultaneously within the same system.

**Problem Statement:**

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) Draw a diagram of the piston-cylinder device.

2) Show the process on a Temperature vs. Specific Volume (T-v) diagram.

---

**Graph/Diagram Explanation:**

1) **Piston-Cylinder Device Diagram:**
- The diagram should depict a closed cylindrical container with a movable piston.
- Inside the cylinder, 1.5 kg of steam is initially present at the given conditions of temperature and pressure.

2) **T-v Diagram (Temperature vs. Specific Volume):**
- Begin by plotting the initial state of steam (300°C, 0.4 MPa).
- Represent the cooling process at constant pressure (isobar) by a horizontal line moving leftwards, indicating a reduction in specific volume as the steam condenses.
- Mark the final state where half of the steam's mass has condensed, showing the significant change in specific volume.
- Highlight the region representing the liquid-vapor mixture as the process moves towards condensation.

This explanation provides a conceptual understanding of the process described in the text for students learning about thermodynamics and phase changes in piston-cylinder devices.
