A thermodynamic cycle x y z x is shown on a V - T diagram. The P - V diagram that best describes this cycle is: (Diagrams are schematic and not to scale)

Step-by-step solution

According to the ideal equation, P V = n R T In the given V ‐ T diagram, In process x → y , V ∝ T . So, the process is isobaric process. In process y → z , V = constant. So, the process is an isochoric process. In process z → x , T = constant. So, the process is an isothermal process. Analyzing using the ideal gas equation in each process, the P ‐ V graph can be drawn as shown below,
