The work done by a gas as it is taken in a cyclic process (shown in the graph) is (in $PV$)

On a $TP$ diagram,two moles of an ideal gas perform processes $AB$ and $CD$. If the work done by the gas in the process $AB$ is two times the work done in the process $CD$,then what is the value of $T_1/T_2$?

$A$ cyclic process for $1 \, \text{mole}$ of an ideal gas is shown in the figure in the $V-T$ diagram. The work done in $AB$, $BC$, and $CA$ respectively is:

Consider a process shown in the figure. During this process,the work done by the system:

In the diagrams $(i)$ to $(iv)$,the variation of volume with changing pressure is shown. $A$ gas is taken along the path $ABCD$. The change in internal energy of the gas will be:

$n$ moles of an ideal gas undergo a process $A \to B$ as shown in the figure. The maximum temperature of the gas during the process is
