(a) Generally, you have four types of unit cell arrangements like 1. Simple cubic 2. Face centered 3. Body-centered 4. Base centered. Can you calculate the number of atoms in each cubic cell? For example, a simple cubic has 1 atom, base-centered has 2 atoms, body-centered has 2 atoms and face-centered has 4 atoms. Explain how these cubic units 1 – 4 have a specified number of atoms.

(b) You have two types of glass solids, both have a cooling rate of 20 oC/s (degree per second) and 40 oC/s. Both have a glass transition temperature 1200 oC, which of them would solidify first, and which one is an easy glass former?
