Match the following
$\begin{array}{|l|l|} \hline Column\,\,-\,\,1 & Column\,\,-\,\,2 \\ \hline P\,:\,Process\,\,-\,\,I & \,\,A\,\,:\,\,Adiabatic \\ \hline Q\,:\,Process\,\,-\,\,II & \,\,B\,\,:\,\,Isobaric \\ \hline R\,:\,Process\,\,-\,\,III & \,\,C\,\,:\,\,Isochoric \\ \hline S\,:\,Process\,\,-\,\,IV & \,\,D\,\,:\,\,Isothermal \\ \hline \end{array}$

$\therefore \,\,\,\,process\,I \to Isochoric;\,P \to C$
As slope of curve $II$ is more than the slope of curve $III$.
$process\,II \to Adiabatic\,and\,processIII \to Isothermal$
$\therefore \,\,\,Q \to A,R \to D$
In process $IV$, pressure is constant
Process $IV \to Isobaric;\,S \to B$
