Kinetic-Molecular Theory and the Nature of Gases.1

Kinetic-Molecular Theory and the Nature of Gases.1. The kinetic-molecular theory applies only to ideal gases. An ideal gas is an imaginary gas that perfectly fits all the assumptions of the kinetic-molecular theory.

How Do Gases Behave?

How Do Gases Behave?. The behavior of gases can be described by the kinetic molecular theory of ideal gases. Gases consist of submicroscopic particles moving about randomly with no attractive forces for one another.
