The volume of one mole gas changes according to the relation $V=\frac{a}{T}$. If temperature change is $\text{Δ}T$, then work done will be,

A cyclic process is shown in the $P-T$ diagram. Which of the following curves show the same process in a $V-T$ diagram?

An ideal gas goes from state $A$ to state $B$ via three different processes as indicated in the $P-V$ diagram.

If $Q_1$, $Q_2$ and $Q_3$ indicate the heat absorbed by the gas along the three processes and $\mathrm{\Delta }{U}_1$, $\mathrm{\Delta }{U}_2$ and $\mathrm{\Delta }{U}_3$ indicate the change in internal energy along the three processes, respectively, then

An ideal monoatomic gas undergoes a cyclic process $ABCA$ as shown in the figure. The ratio of heat absorbed during $AB$ to the work done on the gas during $BC$ is

A $P-T$ diagram is shown below. Choose the corresponding $V-T$ diagram.
