Q. To calculate the amount of work done in joules during reversible isothermal expansion of an ideal gas, the volume must be expressed in
A) $m^{3}\ only$
B) $dm^{3}\ only$
C) $cm^{3}\ only$
D) Any of these
Explanation
(d)
As we know that,
W$ork\ done(W) = 2.303\ nRT\log\frac{V_{2}}{V_{1}}$.
Hence, $V_{1}and\ V_{2}$ are in ratio in the relation. So, unit may be expressed in any one of $m^{3},\ dm^{3}\ or\ cm^{3}$.
