Answer = 0.14 J/m2 = 142 erg/cm2 2 In experiments on

Answer = 0.14 J/m2 = 142 erg/cm2

2 In experiments on homogeneous nucleation, it has been found that solidification of many pure metals can be suppressed to a temperature where G/kT, the exponential term in the nucleation equation, reaches a value of about 30 . Assuming that copper is such a metal, estimate the value of the liquid-solid interfacial energy using the following data. DATA Melting point =1356K Entropy of fusion =2.29cal/(molK) Specific volume =7cm3/mol Maximum observed supercooling is 236K
