various thermodynamic potentials such as F, H, G, the number of second derivative is large. However, the Maxwell relations reduce the number of independent second derivatives. Our goal is to learn how to . Stability conditions for other thermodynamic potentials. Equations used in Legendre transformations: ( ). X. XU.
The minus sign in this equation is to be inferred from the unsymmetrical placement of the arrows in this case. The two remaining rotations of the square give the two additional Maxwell relations and. These are the four most useful Maxwell relations in the conventional applications of thermodynamics. The mnemonic diagram
Maxwell's relations are a set of equations in thermodynamics which are derivable from the symmetry of second derivatives and from the definitions of the thermodynamic potentials. These relations are named for the nineteenth-century physicist James Clerk Maxwell.

Maxwell Relations: A Wealth of Partial Derivatives. Comment On Notation In most textbooks the internal energy is indicated by the symbol U and the symbol E is reserved for the exact energy of a system. Thus E may fluctuate and the internal energy is its mean value, U =<E>. Of course, the essence of thermodynamics is that
Gibbs equation is. du = Tds - Pdv. The enthalpy h can be differentiated,. dh = du + pdv + vdP. Combining the two results in. dh = Tds + vdP. The coefficients T and v The differential expressions for the thermodynamic potentials and Maxwell relations can be remembered conveniently in terms of a thermodynamic Mnemonic

The new scheme here separates the Max Born square into two squares, resulting in easier recalling of several sets of equations, including the.
