Study Notes
Kinetic Molecular Theory Postulates
- Gases are composed of very small particles, which can be atoms or molecules.
- The size of gas particles is negligible compared to the distances between them, allowing the assumption that their volume is insignificant.
- Gas particles are continually in random motion, with frequent collisions against the walls of their container; these interactions generate the pressure exerted by the gas.
- There are no attractions or repulsions between the gas particles; they are considered to move independently of one another.
- The average kinetic energy of gas particles correlates directly with the gas's temperature measured in Kelvin, reflecting principles outlined in Charles' Law.
