Abstract

A comparison between the activation energies for critical nuclei formation obtained from both the classical nucleation theory and Arrhenius kinetic analysis has been proposed. Results obtained indicate that such comparison is hampered by temperature-induced changes of the surface energies, modifying the contact angles and correspondingly the activation energies for nucleation.
