Thus, in order to understand the very difficult concept of Gibbs free energy one must be able to understand its interpretation as Gibbs defined originally by section AB on his figure 3 and as Maxwell sculpted that section on his 3D surface figure.
Da bi se razumeo složen koncept Gibsove slobodne energije neophodno je da se razume njegovo tumačenje originalno definisano sekcijom AB na slici 3, kao i njen Maksvelov prikaz na trodimenzionoj površini.
