The process $AB$ is shown in the diagram. As the gas is taken from $A$ to $B$,its temperature

$A$ 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:

The pressure of an ideal gas varies with volume as $P = \alpha V,$ where $\alpha$ is a constant. One mole of the gas is allowed to undergo expansion such that its volume becomes $m$ times its initial volume. The work done by the gas in the process is

In the diagrams $(i)$ to $(iv)$,the variation of volume with changing pressure is shown. $A$ gas is taken along the path $ABCD$. The change in internal energy of the gas will be:

Find the work done in the cyclic process $ABCA$ shown in the figure.

Four moles of an ideal monoatomic gas undergoes a cyclic process $ABCA$ as shown in the figure. Find the ratio of the temperature of $A$ and $B$.
