Critical free energy for nucleation

LaTeX Go Critical free energy = 16*pi*Surface free energy^3*Melting temperature^2/(3*Latent Heat of Fusion^2*Undercooling value^2)

Critical radius of nucleus

LaTeX Go Critical radius of nucleus = 2*Surface free energy*Melting temperature/(Latent Heat of Fusion*Undercooling value)

Volume free energy

LaTeX Go Volume free energy = Latent Heat of Fusion*Undercooling value/Melting temperature

Critical radius of nucleus (from volume free energy)

LaTeX Go Critical radius of nucleus = -2*Surface free energy/Volume free energy
