CHAPTER 7 Liquids, Solids, and Phase Changes

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.

acidic anhydride	endothermic	mole fraction
	efflorescent	normality
alloy	exothermic	phase equilibrium
boiling point	heat of fusion	polarity
Brownian movement	heat of vaporization	saturated
colligative property	“heavy” water	solute
concentrated	hydrate	solvent
critical pressure	hydrogen bonds	specific gravity
critical temperature	Le Châtelier”s Principle	sublimation
crystal	melting point	surface tension
deliquescent	miscible/immiscible
dilute	molality	viscosity
dynamic equilibrium	molarity
