Calculate the critical radius (in centimeter) of a homogeneous nucleus that forms when pure liquid copper solidifies. Assume Delta T (under cooling) =0.2T_m. Where T_m=1083 degree C. Values for the latent heat of fusion and surface free energy are 1826 J/cm^3 and 177 times 10^-7 J/cm^2, respectively. Calculate the number of atoms in the critical sized nucleus at this under cooling. Copper has FCC crystal structure. Assume a lattice parameter of 0.361 nm for solid copper at its melting temperature
