A
  • The gas contains a very large number of atoms or molecules moving in random directions with random speeds
  • Atoms or molecules of the gas occupy a negligible volume compared with volume of the gas
  • The collisions of atoms or molecules with each other and the container walls are perfectly elastic
  • Time of collisions is negligible
  • Electrostatic forces between atoms or molecules are negligible except during collisions
