Kinetic Molecular Theory Postulates

• Gases consist of molecular particles moving in straight lines at any given instant.

•  lMolecules collide with each other and the container walls without any net loss of energy.

• Gas molecules behave independently -- attractive/repulsive forces between them are negligible.

•  lGas molecules are widely spaced, the actual volume of molecules is negligible compared to the space they occupy.

•  lThe average kinetic energy of the gas particles is proportional to the temperature. Gases consist of molecular particles moving in straight lines at any given instant.
