The correct Answer is:
To determine in which process the P-V (Pressure-Volume) diagram is a straight line parallel to the volume axis, we can analyze the characteristics of different thermodynamic processes. ### Step-by-Step Solution: 1. **Understanding the P-V Diagram**: - The P-V diagram plots pressure (P) on the y-axis and volume (V) on the x-axis. - A straight line parallel to the volume axis indicates that pressure remains constant while volume changes. 2. **Identifying the Characteristics of Processes**: - **Isobaric Process**: In this process, the pressure remains constant (P = constant) while the volume can change. This means that if we were to plot this on a P-V diagram, it would appear as a horizontal line (parallel to the volume axis). - **Isochoric Process**: In this process, the volume remains constant (V = constant) while pressure can change. This would appear as a vertical line (parallel to the pressure axis). - **Isothermal Process**: In this process, the temperature remains constant, and the curve is hyperbolic, not a straight line. - **Adiabatic Process**: This process also does not yield a straight line on the P-V diagram; it is represented by a curve. 3. **Conclusion**: - Since we are looking for a straight line parallel to the volume axis, we conclude that the process being described is an **Isobaric Process**. ### Final Answer: The process in which the P-V diagram is a straight line parallel to the volume axis is the **Isobaric Process**.
