Now that all the phases of a substance have been studied we need to come up with a convenient way to represent all of this information. A phase diagram is a graphical representation used to depict which phase(s) is/are present during certain pressures and temperatures.
The last part of Chapter 11 deals with solids. The functional components in smart phones, laptops, and flat screen tv's consist of solids and modern materials. In order to improve the functionality of these devices we must have a common knowledge of the bonding in solids.
There are two general types of solids, amorphous and crystalline. In crystalline solids the particles order in a well-defined repeating pattern and we can analyze how the atoms/ions pack in these solids. After defining unit cells and crystal lattices, three types of cubic unit cells were investigated and this information can be used to determine density and Avagadros number.
