1) In general, should simple cubic, body-centred cubic, or face-centred cubic metals have

the highest surface energy? Explain your reasoning

2) How much more energy does it take to mold a drop of molten steel with radius 5 cm into

a square sheet with 1 mm thickness than into a cube. The surface energy of molten

steel at the molding temperature is 0.5 J/m2 and the volume of steel does not change.

Assume the only energies involved are surface energies.
