Test Your Knowledge of Kinetic Molecular Theory

Kinetic molecular theory is a scientific theory that explains the behavior of particles in matter.

The basic assumptions of kinetic molecular theory are that all matter is made up of small particles (atoms, molecules, or ions) that are in constant motion, the particles are constantly colliding with each other and with the walls of their container, and the average kinetic energy of the particles is proportional to the temperature of the substance.

Kinetic molecular theory explains many of the physical properties of matter, such as temperature, pressure, and volume.
