Ideal Gas has the following properties:

I. An ideal gas consists of a large number of identical molecules.

II. The volume occupied by the molecules themselves is negligible compared by the volume occupied by the gas.

III. The molecules does not obey Newton’s Law of Motion.

IV. The molecules experience forces only during collisions; any collisions are completely elastic, and take a negligible amount of time.

• I, II, and III are true

• I, II, and IV are true

• All of the statements are true
