Key Concepts

Random Motion

Kinetic molecular theory assumes that gas particles are in constant, random motion. This means they continuously move and change direction as they collide with one another and the walls of their container.

Temperature and Kinetic Energy

A central idea in the kinetic molecular theory is that the average kinetic energy of the gas molecules is directly proportional to the absolute temperature. As the temperature increases, so does the average speed and kinetic energy of the molecules.

Negligible Molecular Volume

The theory assumes that the volume of the individual gas molecules is negligible compared to the volume occupied by the gas. This idealization allows gases to be treated as point particles, simplifying the analysis of their behavior.

Elastic Collisions

An important concept is that the collisions between gas molecules, and between molecules and the walls of a container, are perfectly elastic. In such collisions, there is no net loss of kinetic energy, ensuring the conservation of energy during interactions.

Absence of Intermolecular Forces

Kinetic molecular theory postulates that gas particles do not exert significant attractive or repulsive forces on each other except during collisions. This assumption helps explain the free and random motion of the particles in an ideal gas.
