For each of the following classes of materials, give two specific examples that are a regular part of your life: (a) metals; (b) ceramics (glasses); (c) polymers; (d) semiconductors; Specify the object that each material is found in and explain why the material is used in each specific application. Hint: One example answer for part (a) would be that aluminum is a metal used in the base of some pots and pans for even heat distri-bution. It is also a lightweight metal that makes it useful in kitchen cookware. Note that in this partial answer to part (a), a specific metal is described for a specific application.
