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

Options:

Answer:

Solution:

For process $3 \to 1$ , Volume is constant,
$P V = n P T;$ as P increases T increases.
For process $1 \to 2$ , the process is adiabatic process,
$P V^{γ} =$ Constant
$\Rightarrow T V^{γ - 1} =$ Constant.
For process $2 \to 3$ , pressure is constant,
$V = k T$ .
