Q1/ In a homogeneous solidification process, assume molten metal solidifies into a spherical nucleus with a BCC structure. The given data are; lattice parameter (0.292 nm), the heat of fusion energy (1.85x109 J/m³), latent surface free energy (0.204 J/m2), critical radirus (1-35 nm), equilibrium melting temperature (1516 K), and room temperature (27 °C). Calculate the following for this metal; no. ol (a) supercooling value temperature (b) activation free energy (c) number of atoms in a nucleus of critical size. t hoth ends The wave vibrates in
