Q. To calculate the amount of work done in joules during reversible isothermal expansion of an ideal gas, the volume must be expressed in:

Solution:

As we know that,
Work done $(W)=2.303 \,n R T \log \frac{V_{2}}{V_{1}}$
Hence, $V_{1}$ and $V_{2}$ are in ratio in the relation. So, unit may be expressed in any one of $m ^{3}, dm ^{3}$ or $cm ^{3}$
