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

The following figure shows two processes $A$ and $B$ for a gas. If $\Delta Q_A$ and $\Delta Q_B$ are the amounts of heat absorbed by the system in the two cases,and $\Delta U_A$ and $\Delta U_B$ are the changes in internal energies,respectively,then:

What is the total work done in a cyclic process?

$A$ mole of an ideal diatomic gas undergoes a transition from $A$ to $B$ along a path $AB$ as shown in the figure. The change in internal energy of the gas during the transition is ...... $kJ$.

In the given $P-V$ diagram,the initial state of an ideal gas is represented by point $a$ and the final state by point $e$. The gas moves from state $a$ to state $e$ along paths $(i) abe, (ii) ace, (iii) ade$. The heat absorbed by the gas will be:

The $p-V$ diagram for a fixed mass of an ideal gas undergoing a cyclic process is as shown in the figure. $AB$ represents an isothermal process, $BC$ represents an isobaric process, and $CA$ represents an adiabatic process. Which one of the following graphs represents the $p-T$ diagram of this cyclic process?
