Maxwell Relations
From the Euler reciprocity relation shown in Eq. (B-
13) of Appendix B, we can write
Therefore
Equation (4.2-10) is called Maxwell relations. A common use
of these relations is to replace a partial derivative that is hard
to measure with one that can more easily be measured. For
example, it would be difficult to measure (∂P/∂S) V,n , but much
easier to measure (∂T /∂V) S,n .
