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 C_{P}, i.e.,

we get,

→ (4.3)
From the Maxwell relation 3
,

Substituting these in Equn.4.2,

→ (4.4)
