Webinternal energy, in thermodynamics, the property or state function that defines the energy of a substance in the absence of effects due to capillarity and external electric, magnetic, and other fields. Like any other state function, the value of the energy depends upon the state of the substance and not upon the nature of the processes by which it attained that state. In … Web4.3. THE PARTITION FUNCTION AND THE FREE ENERGY 98 4.3. The partition function and the free energy The partition function is of physical significance itself, as shown by the following theorem. Z = e−βF; F = −k B T lnZ. (4.8) 4.3.1. First proof: average of F We will show this in two ways. First we need to interpret F in the equation.
