$A$ monoatomic ideal gas goes through a cyclic process as shown in the figure. The efficiency of this process is (in $\%$)

The given diagram shows four processes,i.e.,isochoric,isobaric,isothermal,and adiabatic. The correct assignment of the processes,in the same order,is given by

$A$ 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:

$A$ thermodynamic system is taken from an original state to an intermediate state by the linear process shown in the figure. Its volume is then reduced to the original value from $E$ to $F$ by an isobaric process. Calculate the total work done (in $J$) by the gas from $D$ to $E$ to $F$.

The $P-V$ diagram shows a cyclic process for a thermodynamic engine containing a monoatomic ideal gas. The energy absorbed from the heat source during one complete cycle is .......

Work done for the process shown in the figure is ............ $J$
