An indicator diagram is a ...........

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

$A$ gas in a closed container undergoes the cycle $ABCA$ as shown in the figure. The net heat absorbed by the gas after it has completed $10$ cycles is

The $P-V$ diagram of an ideal gas is as shown. Find the work done by the gas in the $ABCD$ process.

The figure given below shows the variation in the internal energy $U$ with volume $V$ of $2.0 \text{ mole}$ of an ideal gas in a cyclic process $abcda$. The temperatures of the gas during the processes $ab$ and $cd$ are $500 \text{ K}$ and $300 \text{ K}$ respectively. The heat absorbed by the gas during the complete process is .... $J$. (Take $R = 8.3 \text{ J/mol-K}$ and $\ln 2 = 0.69$)

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