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

    A)  \[d{{m}^{3}}\]only                        

    B)  \[{{m}^{3}}\]only

    C)  any unit                              

    D)  \[c{{m}^{3}}\]unit

    Correct Answer: C

    Solution :

    We know that work done during reversible isothermal expansion, \[{{W}_{re\upsilon }}=2.303\,nRT\,\log \frac{{{V}_{2}}}{{{V}_{1}}}\]
