Six moles of an ideal gas perform the cycle shown in the figure. If the temperatures are $T_A = 600 \, K$, $T_B = 800 \, K$, $T_C = 2200 \, K$, and $T_D = 1200 \, K$, the work done per cycle is ........ $kJ$.

$A$ gas system is taken through the thermodynamic cyclic process $1 \rightarrow 2 \rightarrow 3 \rightarrow 1$ as shown in the figure. The amount of heat released by the system is

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?

One 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

$A$ thermodynamic system is taken from an original state $A$ to an intermediate state $B$ by a linear process as shown in the figure. Its volume is then reduced to the original value from $B$ to $C$ by an isobaric process. The total work done by the gas from $A$ to $B$ and $B$ to $C$ is: (in $J$)

One mole of an ideal gas is taken from $A$ to $B$,from $B$ to $C$,and then back to $A$. The variation of its volume with temperature for that change is as shown. Its pressure at $A$ is $P_{0}$ and volume is $V_{0}$. Then,the internal energy:
