Sethna says \Thermodynamics is a zoo of partial derivatives, transformations and relations". Thermodynamics is summarized by its Four laws, which are established upon a large number of empirical observations.... The 4 Maxwell Relations (Derivations) In these notes the four Maxwell Relations are derived from the four thermodynamic potentials. Notes of the four thermodynamic potentials …

### One may conveniently employ general energy relations and Maxwell equations to obtain the expressions for change in enthalpy and entropy and internal energy for any process, which in turn may be used for computing the associated heat and work interactions.

- as the Maxwell relations (although Maxwell’s main claim to fame is, of course, his uniﬁcation of electricity and magnetism and subsequent predic- tion of electromagnetic radiation, he also made important contributions to
- In 2001, Ambegaokar and Mermin [10] pointed out that the way to look at the Maxwell relations within the context of the Jacobian identities is little known in thermodynamic standard textbooks.

- The thermodynamic square can be used as a mnemonic to recall and derive these relations. The four most common Maxwell relations are the equalities of the second derivatives of each of the four thermodynamic potentials. with respect to their thermal natural variable (temperature T. enthalpy H(S. .
