Starting with a cube of solid, 1 cm along each edge, what is the total surface area when the solid is subdivided into cubes lop4 cm on each edge? Repeat the calculation for lop5 cm and lop6 cm cubes. Calculate the surface energy per particle in each case, assuming the surface energy is 70 mJ m-' and compare this with thermal energy (kT) at room temperature (25 “C). What is the total surface energy for each system?
