One mole of a monatomic ideal gas undergoes the cyclic process $J \rightarrow K \rightarrow L \rightarrow M \rightarrow J$, as shown in the $P - T$ diagram.

Match the quantities mentioned in $List-I$ with their values in $List-II$ and choose the correct option. [ $R$ is the gas constant]

$List-I$ $List-II$
($P$) Work done in the complete cyclic process ($1$) $R T_0-4 \ R T_0 \ln 2$
($Q$) Change in the internal energy of the gas in the process $JK$ ($2$) $0$
($R$) Heat given to the gas in the process $KL$ ($3$) $3 \ R T_0$
($S$) Change in the internal energy of the gas in the process $MJ$ ($4$) $-2 \ R T_0 \ln 2$
  ($5$) $-3 \ R T_0 \ln 2$

$\Delta U =\frac{3}{2} nR \left(2 T _0\right)=3 nRT _0$

$KL \rightarrow \text { isothermal } \rightarrow W = nR (3 T ) \ln \left(\frac{1}{2}\right)=-3 nRT _0 \ln 2$

$\Delta U =0 \Rightarrow Q =-3 nRT _0 \ln 2$

$LM \rightarrow \text { isobaric }=2 P _0\left(- V _0\right)=-2 nRT _0$

$MJ \rightarrow \text { isothermal } \Rightarrow nRT _0 \ell n 2 ; \Delta U =0$

$WD _{ xat }=-2 nRT _0 \ln 2$
