Following graph shows four different processes, adiabatic, isothermal, isobaric and isochoric for an ideal gas, from the same initial state. Study the graph carefully and state which of the following statements is correct?

Step-by-step solution

From the given P-V graph, we can analyze the four processes starting from the same initial state: 1. Process 1 is a vertical line parallel to the P -axis. This indicates that the volume V remains constant while the pressure changes. Therefore, Process 1 is an isochoric process. 2. Process 4 is a horizontal line parallel to the V -axis. This indicates that the pressure P remains constant while the volume changes. Therefore, Process 4 is an isobaric process. 3. Processes 2 and 3 are curves representing expansion (vol
