Which of the following is an equivalent cyclic process corresponding to the thermodynamic cyclic given in the figure? Where, 1 → 2 is adiabatic. (Graphs are schematic and are not to scale)

Step-by-step solution

For process 3 → 1 , Volume is constant, P V = n P T ; as P increases T increases. For process 1 → 2 , the process is adiabatic process, P V γ = Constant ⇒ T V γ - 1 = Constant. For process 2 → 3 , pressure is constant, V = k T .
