Q

assumptions of kinetic molecular theory of gases

A
  • particles have negligible volume
  • no intermolecular attractions or repulsions
  • molecule are in continuous random motion
  • collisions are elastic (no overall gain or loss of energy)
  • average kinetic energy of particles is proportional to the absolute temperature.
