Which of the following relationships is valid only for reversible processes undergone by a closed system of simple compressible substance (neglect changes in kinetic and potential energy)?
-
- δQ = dU + δW
- TdS = dU + pdV
- TdS = dU + δW
- δQ = dU + pdV
Correct Option: B
Q = dU + PdV
Reversible closed system
| = ds ← Reversibe | T |
TdS = du + Pdv
