$A$ sample of an ideal monoatomic gas is taken around the cycle $ABCA$ as shown in the figure. The work done during the cycle is

An ideal gas is taken through the process shown in the figure. Which statement is true?

The heat absorbed by a system in going through the given cyclic process is: (in $\,J$)

One mole of an ideal gas in initial state $A$ undergoes a cyclic process $ABCA$,as shown in the figure. Its pressure at $A$ is $P_0$. Choose the correct option$(s)$ from the following:
$(A)$ Internal energies at $A$ and $B$ are the same
$(B)$ Work done by the gas in process $AB$ is $P_0 V_0 \ln 4$
$(C)$ Pressure at $C$ is $\frac{P_0}{4}$
$(D)$ Temperature at $C$ is $\frac{T_0}{4}$

The density $\rho$ versus volume $V$ graph is shown in the figure. Find the corresponding pressure $P$ versus temperature $T$ graph.

An ideal gas is taken from point $A$ to point $C$ on a $P-V$ diagram through two processes $AOC$ and $ABC$ as shown in the figure. Process $AOC$ is isothermal.
