Using the information in the table, determine the value of the critical radius, r, and the maximum value of GT for the homogeneous nucleation of iron at maximum undercooling. (Round the final answers to three decimal places.) Value for the Freezingtemperature, heat of fusion, surface energy, and maximum undercooling for selected metals The critical radius is 107cm. The maximum value of GT is 1018J
