For the Solidification of Copper, Calculate the size of the critical radius and the number of atoms in the critical nucleus when solid copper forms by homogeneous nucleation. Comment on the size of the nucleus and assumptions we made while deriving the equation for the radius of the nucleus What are the expected total number atoms in the nucleus (atoms/nucleus)? Given: Amount of undercooling, AT = 236°C, Latent heat of fusion, AH, = 1628 J/cm Surface free energy y = 177x107 cm. The unit cell (FCC) length, a, is 0.3615 nm.
