ABCD

Show answer and solution▾

Answer: (C)

For process $3\rightarrow 1$, Volume is constant,
$PV=nPT;$ as P increases T increases.
For process $1\rightarrow 2$, the process is adiabatic process,
$P{V}^{\gamma }=$ Constant
$\Rightarrow T{V}^{\gamma -1}=$ Constant.
For process $2\rightarrow 3$, pressure is constant,
$V=kT$.
