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?

Work and Heat Transfer

It is generally related to thermal engineering which tells about the use, creation, conversion and transfer of heat energy between the systems. It is also considered that to transfer heat from one source to another, transfer of masses is also required. There are various mechanisms by which, transfer of heat takes place i.e. thermal conduction, convection, radiation or by change of phase. All these mechanisms have their own specific features which sometimes occur simultaneously within the same system.
