1. A sugar cube will balance on a soccer ball, but a
sugar cube will not balance on a dried pea. What is the
radius of the sphere (in terms of the edge length of
the sugar cube) where the sugar cube is in neutral
equilibrium?
2. A gram of water is super-cooled to -40 C. It
spontaneously undergoes a phase change to a mixture of
water-ice. What is the change in entropy?
