Liquids, Solids, and Phase Changes

Chapter Summary

The following terms summarize all the concepts and ideas that were introduced in this chapter. You should be able to explain their meaning and how you would use them in chemistry. They appear in boldface type in this chapter to draw your attention to them. The boldface type also makes it easier for you to look them up if you need to. You could also use the search or “Google” action on your computer to get a quick and expanded explanation of these terms, laws, and formulas.
