The Helmholtz free energy

The Helmholtz free energy. plays an important role for systems where T, U and V are fixed. - F is minimum in equilibrium, when U,V and T are fixed!. by using:. immediate relations:. Maxwell relation:. Calculation of the Helmholtz free energy (F) from the partition function (Z):
