A thermodynamic cycle x y z x is shown on a V - T diagram. The P - V diagram that best describes this cycle…

According to the ideal equation,

$PV=nRT$

In the given $V‐T$ diagram,

In process $x\to y$, $V\propto T$. So, the process is isobaric process.

In process $y\to z$, $V=$ constant. So, the process is an isochoric process.

In process $z\to x$, $T=$ constant. So, the process is an isothermal process.

Analyzing using the ideal gas equation in each process, the $P‐V$ graph can be drawn as shown below,
