An ideal gas has undergone a cyclic process as shown in the figure. The work done by the gas in the entire cycle is . . . . . . $\times 10^{-1} \ J$. (Take $\pi = 3.14$)

$A$ system goes from $A$ to $B$ via two processes $I$ and $II$ as shown in the figure. If $\Delta U_I$ and $\Delta U_{II}$ are the changes in internal energies in the processes $I$ and $II$ respectively,then:

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

$A$ thermodynamic system undergoes a cyclic process $ABCDA$ as shown in the figure. The work done by the system in the cycle is

$A$ thermodynamic cycle $xyzx$ is shown on a $V-T$ diagram.
The $P-V$ diagram that best describes this cycle is
(Diagrams are schematic and not to scale)

In the following $p-V$ diagram, the equation of state along the curved path is given by $(V-2)^2 = 4aP$, where $a$ is a constant. The total work done in the closed path is:
