Question 808: Thermodynamics & KTG

Question

Which of the following graphs between pressure (P) and volume (V) correctly shows isochoric changes?

Accepted Answer

Isochoric processes are those in which the volume of the system remains constant. In a Pressure-Volume (P-V) graph, an isochoric process is represented by a vertical line because the volume does not change, while the pressure can vary.
Looking at the provided graph :
Graph A shows a diagonal line, indicating changes in both pressure and volume.
Graph B shows a horizontal line, indicating constant pressure, not constant volume. This represents an isobaric process.
Graph C shows a vertical line, which is characteristic of an isochoric process, where the volume remains constant while the pressure changes.
Graph D shows a curve, indicating that both pressure and volume are changing.
Therefore, the correct option that represents an isochoric process is :
