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?
- A Process 4 is adiabatic
- B Process 1 is isochoric
- C Process 2 is isobaric
- D Process 3 isochoric
Answer & Solution
Correct Answer
(B) Process 1 is isochoric
Step-by-step Solution
Detailed explanation
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…
