Chemical Engineering Thermodynamics
Which of the following identities can be most easily used to verify steam table data for superheated steam.

(∂P/∂T)V = (∂S/∂V)T

(∂V/∂T)P = -(∂S/∂P)T

(∂T/∂V)S = (∂p/∂S)V

(∂T/∂P)S = (∂V/∂S)P

(∂P/∂T)V = (∂S/∂V)T

(∂V/∂T)P = -(∂S/∂P)T

(∂T/∂V)S = (∂p/∂S)V

(∂T/∂P)S = (∂V/∂S)P
