$A$ thermodynamic system is taken through a cyclic process as shown in the $P-V$ diagram. The total work done in the process is $.........\,J$.

An ideal system can be brought from state $A$ to $B$ through four paths as shown in the figure. The energy given to the system is minimum in

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 $T_1/T_2$?

What is the net work done in the process shown in the $P-V$ diagram?

$A$ system goes from $A$ to $B$ via two processes $I$ and $II$ as shown in the figure. If $\Delta U_1$ and $\Delta U_2$ are the changes in internal energies in the processes $I$ and $II$ respectively,then:

In the following indicator diagram,the net amount of work done will be
