2. At an undercooling of 10K, determine the concentration of solid-like clusters of Cu atoms containing 10,50,100,110,120,130,140 and 150 atoms. How many atoms are in a critical nucleus at this temperature? Melting Temperature of Cu:1356K Enthalpy of Fusion of Cu: 12,970J/mol Solid/Liquid Interfacial Energy Parameter for Cu:0.177J/m2 Molar Volume of Liquid Cu: 8.0106m3/mol
