What is the kinetic assumptions are made when dealing with ideal gas? (5)

1. The gas contains a large number of molecules moving in random direction at random speeds 2. Electrostatic forces between molecules is negligible, except during collisions. 3. Collisions are perfectly elastic 4. Time of collision between molecules is negligible compared to time between collisions 5. The molecules of a gas occupy negligible volume compared to the total volume of the gas.
