a) A material that you are working with has a band gap of 4 eV but it is opaque (doesn't transmit light) because it contains many pores. Explain the mechanism for low light transmission in this material.

b) Why do materials tend to expand with temperature?

c) You are working with an new material and have no idea of its heat capacity. What is a reasonable estimate? Why?
