The image depicts a Pressure-Volume (PV) diagram illustrating a thermodynamic process. **Diagram Explanation:** - **Axes:** - The vertical axis is labeled as \( P \) (Pressure) - The horizontal axis is labeled as \( V \) (Volume) - **Points:** - Point \( A \) is at the intersection of lower pressure and volume. - Point \( B \) is at a higher pressure and maintains the same volume as point \( C \). - Point \( C \) shares the same volume as point \( A \), maintaining a constant pressure. - **Process Path:** - The process starts at point \( A \), moves to point \( B \), signifying an increase in both pressure and volume. - From \( B \), it moves vertically to point \( C \) without a change in volume, indicating a decrease in pressure. - Lastly, the path returns from point \( C \) to point \( A \) horizontally, maintaining constant pressure while reducing volume. - **Arrows:** - Arrows indicate the direction of the thermodynamic cycle: \( A \rightarrow B \rightarrow C \rightarrow A \). This diagram is typically used to represent cycles in thermodynamic engines, such as the Carnot cycle, and provides a visual representation of how pressure and volume change during different processes.
