(choose chapter or problem)

The Helmholtz function of a substance has the form

\(a=-R T \ln \frac{\nu}{\nu_{0}}-c T_{0}\left(1-\frac{T}{T_{0}}+\frac{T}{T_{0}} \ln \frac{T}{T_{0}}\right)\)

where \(T_{0}\) and \(v_{0}\) are the temperature and specific volume at a reference state. Show how to obtain \(P, h, s, c_{v}\), and \(c_{p}\) from this expression.
