Question

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

Tardigrade Admin · Accepted Answer

Work done in a reversible isothermal expansion may be given as: W=2.303 nRT log (V2/V1), as V2 and V1 are taken in a ratio. Thus, the unit taken does not matter.

Work done in a reversible isothermal expansion may be given as :

$W = 2.303 n RT lo g \frac{V _{2}}{V _{1}}$ , as

$V_{2}$ and $V_{1}$ are taken in a ratio.

Thus, the unit taken does not matter.
