Module 4: Phases/States of Matter

Description: Properties of the four states of matter and transitions between them.

Length of Time: 4 hours


1. Solid State

2. Liquid State

3. Gas State

4. Ionic State

5. Sublimation, condensation, & vaporization

6. Vapor pressure


Student Objectives:

Student will be able to:

1. Define the four states of matter: solid, liquid, gas, and ionic.

2. Describe the processes involved when matter changes from one state to another.

3. Define the terms: sublimation, condensation, and vaporization.

4. Give an example of a material that sublimates.

5. Given a graph of vapor pressure versus temperature, determine the vapor pressure of a given material at a given temperature and relate that vapor pressure to vacuum system performance.

6. Given examples of semiconductor manufacturing processes, indicate which one function as a result of sublimation, condensation, or vaporization.
