In this chapter, you will expand your understanding of the kinetic-molecular theory as you study liquids and solids. You will relate intermolecular forces in liquids to viscosity and surface tension. Four categories of solids will be described and related to the structure and bonding in each. You will also learn about changes of state and how to interpret phase diagrams.

In this chapter, you will learn: to explain how the kinetic-molecular theory accounts for the physical properties of liquids and solids to describe the different types of intermolecular forces to define viscosity and surface tension to compare crystalline and amorphous substances to describe vaporization, condensation, boiling, freezing, and melting to identify the features of a phase diagram
