Moreover, W = ∫ V i V f P d V . {\displaystyle W=\int _{V_{i}}^{V_{f}}P\,dV.} where W {\displaystyle W} denotes the work done by the system during the whole of the reversible process.
Maka, W = ∫ V i V f P d V . {\displaystyle W=\int _{V_{i}}^{V_{f}}P\,dV.} dengan W {\displaystyle W} menunjukkan kerja yang dilakukan oleh sistem selama proses reversibel keseluruhan.
