Web4 mrt. 2013 · The Helmholtz free energy of the van der Waals gas can be written as follows: F(T,V,N) = −Nk BT 1+log (V −Nb′)T3/2 Nc′ − a′N2 V , (1) where a′, b, and c′are constants (i.e., independent of T, V, and N). We will first re-express this equation in the following way: 1. Volume and free energy are divided by N, thus making them intensive.
