The Fundamentals of Kinetic Molecular Theory (KMT) The molecules of a gas are in a state of perpetual motion in which the velocity (that is, the speed and direction) of each molecule is completely random and independent of that of the other molecules.
The kinetic-molecular theory explains the states of matter, and is based on the idea that matter is composed of tiny particles that are always in motion. This theory helps explain observable properties and behaviors of solids, liquids, and gases.
The experimental observations about the behavior of gases discussed so far can be explained with a simple theoretical model known as the kinetic molecular theory. This theory is based on the following postulates, or assumptions.

The kinetic molecular theory (KMT) is a simple microscopic model that effectively explains the gas laws described in previous modules of this chapter. This theory is based on the following five postulates described here.
What is the Kinetic Molecular Theory? Kinetic molecular theory is a theory that explains the behavior of a gas in terms of the motion and interactions of its constituent particles, which are typically atoms or molecules.
The kinetic molecular theory (KMT) is a simple microscopic model that effectively explains the gas laws described in the previous sections of this chapter. This theory is based on the following five postulates described here.
Key concepts. Terms you should know. If you’ve ever changed an old incandescent light bulb, you might have noticed what looks like black powder coating the inside of the bulb. That black coating is actually metal atoms that escaped from the bulb’s tungsten filament and condensed on its glass (Figure 1).
Kinetic molecular theory states that gas particles are in constant motion and exhibit perfectly elastic collisions. Kinetic molecular theory can be used to explain both Charles’s and Boyle’s laws. The average kinetic energy of a collection of gas particles is directly proportional to absolute temperature only. Key Terms.
The kinetic-molecular theory (KMT) is a simple molecular model that effectively explains the physical properties of matter using the motion of the molecules. This theory, focusing on gases, is based on the following five postulates described here.
