For a sample of perfect gas when its pressure is changed isothermally from pi to pf, the entropy change is given by
- \(\Delta S=n R T \ln \left(\frac{p_{f}}{p_{i}}\right)\)
- \(\Delta S=R T \ln \left(\frac{p_{i}}{p_{f}}\right)\)
- \(\Delta S=n R \ln \left(\frac{p_{f}}{p_{i}}\right)\)
- \(\Delta S=n R \ln \left(\frac{p_{i}}{p_{f}}\right)\)
Answer
(D) S=n R ( p_ i p_ f )
