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

Options

A.
B.
C.
D.

Answer

A

Explanation

For process 3 to 1,
Volume is constant
PV = nRT, as Pincreases T increases
For process 1 to 2,
`PV^(gamma)` = constant `implies TV^(gamma-1)` = Constant
For process 2 to 3, Pressure is constant V=kt.
