    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)  \[d{{m}^{3}}\] only

    C)  \[c{{m}^{3}}\] only                        

    D)  Any of these

    Correct Answer: D

    Solution :

                     Work done in reversible isothermal expansion of an ideal gas can be calculated by using the following relation                 \[W=2.303\,\,nRT\,{{\log }_{10}}\frac{{{V}_{2}}}{{{V}_{1}}}\] Here \[{{V}_{1}}\] and \[{{V}_{2}}\] are in the ratio, therefore, to calculate work done in joules the volume may be expressed in any one of \[{{m}^{3}},d{{m}^{3}}\] or \[c{{m}^{3}}\].
