1. describe the solid state according to the kinetic-molecular theory.
2. what is the difference between an amorphous solid and a crystalline solid?
3. account for each of the following properties of solids: the definite volume, the relatively high density of solids, the extremely low rate of diffusion.
4. Compare and contrast the four types of crystals.
5. why do crystalline solids shatter into regularly shaped fragments when broken?
6. Explain why ionic crystals melt at much higher temperatures than typical covalent molecular crystals.
