Kinetic Molecular Theory All matter is composed of small particles. Particles of matter are in constant motion. Particle collisions are elastic. (No transfer of energy/loss of energy in a collision) Gases only: Volume of each gas particle is negligible compared to the volume of the sample. Particles of gases exert no forces of attractions on each other. (This is due to the great distance between molecules.) Ideas of KMT explain ideal gas behavior. Deviations of ideal gas behavior occur among real gases because real gases do have volume and IMF?s. Deviations are minimized under conditions of low pressure and high temperature (PLIGHT) Hydrogen and helium behave most like ideal gases due to their small size and very weak IMFs.
