$A$ thermodynamic system is taken through the cycle $PQRSP$ as shown in the $P-V$ diagram. The net work done by the system is ....... $J$.

An ideal gas undergoes a cyclic process $ABCDA$ as shown in the given $p-V$ diagram. What is the magnitude of the amount of work done by the gas?

Three different processes that can occur in an ideal monoatomic gas are shown in the $P$ vs $V$ diagram. The paths are labelled as $A \rightarrow B, A \rightarrow C$ and $A \rightarrow D$. The change in internal energies during these processes are taken as $E_{AB}, E_{AC}$ and $E_{AD}$ and the work done as $W_{AB}, W_{AC}$ and $W_{AD}$. The correct relation between these parameters is:

The pressure and volume of a gas are changed as shown in the $P-V$ diagram in this figure. The temperature of the gas will ........

One mole of a monoatomic gas is carried along the process $ABCDEA$ as shown in the diagram. Find the net work done by the gas in $J$.

As shown in the figure,the amount of heat absorbed along the path $ABC$ is $90\,J$ and the amount of work done by the system is $30\,J$. If the amount of work done along the path $ADC$ is $20\,J$,the amount of heat absorbed will be .... $J$.
