5 rules of the kinetic molecular theory of gases
1. a gas consists of small particles that move randomly with rapid velocities
2. The attractive forces between the particle of a gas can be neglected
3. The actual volume occupied by gas molecules is extremely small compared to the volume that the gas occupies
4. the average kinetic energy of gas molecules is proportional to the kelvin temperature
5. Gas particles are in constant motion, moving rapidly in straight paths
