\(W\,\, = \,\, - \,2.303\,\,nRT\,\,\log \,\frac{{{V_2}}}{{{V_1}}}{\text{ }} \)
\( n\, = \,\,2,\,R\,\, = \,\,8.314,\,\,T\,\, = \,\,298\,K,\,\,{V_2}\, = \,\,20L,\,\,{V_1}\,\, = \,\,10L \)
\( W\,\, = \,\, - \,2.303\,\, \times \,\,2\,\, \times \,\,8.314\,\, \times \,\,298\,\,\log \,\frac{{20}}{{10}}\,\,\, \Rightarrow \,\,W\, = \, - \,3434.9\,J \)
