Thermodynamics Relations - Proof 4

Home -> ChE Learning Resources -> Solved Problems -> Thermodynamics-> Property Relations



Considering S as a function of the independent variables T and P

   → (4.1)    → (4.2)

From fundamental property relation IV,

dividing by dT, at constant pressure,

and by the definition of CP, i.e.,

we get,

   → (4.3)

From the Maxwell relation 3 ,

Substituting these in Equn.4.2,

   → (4.4)
