Thermodynamic Partials - Maxwell's Relation - Under the Hood A partial derivative is an operation that you can apply to (multi-variable) functions. but I haven't really seen any problems in which you use the relations. This is excluding any energy from outside of the system (due to any external forces) or the kinetic energy of a system as a whole. Now since under appropriate conditions = and then . Maxwell relations are extremely valuable in thermodynamics because they provide a means of determining the change in entropy, which cannot be measured directly, by simply measuring the changes in properties P, v, and T. These Maxwell relations are limited to simple compressible systems. It is seen that for every thermodynamic potential there are n ( n 1)/2 possible Maxwell relations where n is the number of natural variables for that potential. In thermodynamics, the Maxwell equations are a set of equations derived by application of Euler's reciprocity relation to the thermodynamic characteristic functions.
