The $P-V$ graph of an ideal gas cycle is shown below. The adiabatic processes are described by:

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 ........

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:

$A$ 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 $F$.

Calculate the heat given to the gas during the cyclic process $ABA$ shown in the figure (in $J$).

The net work done by an ideal gas going through the cycle as shown in the $P-V$ diagram below is
