Kinetic molecular theory provides a fundamental understanding of gases by describing how gas particles behave in terms of their motion. This theory posits that gases are composed of numerous small particles that are in constant, random motion. It emphasizes aspects such as the speeds of these particles, the distances between them, and the way they collide with one another and with the walls of their container.

This understanding of particle motion is crucial in explaining various gas behaviors, such as pressure, temperature, and volume relationships, which are encapsulated in the ideal gas law. Thus, the behavior of gases is primarily governed by their kinetic energy, which is directly related to temperature – the higher the temperature, the faster the particles move. In contrast, the other options focus on the behavior of solids or the nature of chemical bonds, which are not the focus of kinetic molecular theory.
