7.2. In Ex. 7.5 an expression is found for the Joule/Thomson coefficient, μ = (@T/P)² that relates it to a heat capacity and equation-of-state information. Develop similar expressions for the derivatives: (a) (@TIOP)S (b) (at lav)u What can you say about the signs of these derivatives? For what types of processes might these derivatives be important characterizing quantities?
