Preferred Label : second-order transition;
IUPAC definition : A transition in which a crystal structure undergoes a continuous change and in which
the first derivatives of the Gibbs energies (or chemical potentials) are continuous
but the second derivatives with respect to temperature and pressure (i.e. heat capacity,
thermal expansion, compressibility) are discontinuous. Example: The order–disorder
transition in metal alloys, for example, CuZn. Synonymous with continuous transition.;
