This chapter describes the particle nature of gases, liquids, and solids. The kinetic theory of matter is presented as a model that explains properties of each state of matter and accounts for changes of state. You will learn to describe gases, liquids, and solids on a particle basis and explain what happens during the interconversion of these three states of matter.

In this chapter, you will learn: to describe the motion of gas particles to interpret gas pressures to describe the nature of a liquid in terms of attractive forces to differentiate between evaporation and boiling to describe how the degree of organization of particles distinguishes solids from gases and liquids to interpret the phase diagram of water
