Ideal Gas equation and its Assumptions The two assumptions are that the gases are points of mass that move, they have no volume and that there is no interaction between other molecules.

But even the points of mass can collide with each other so wouldn't that be considered interaction between molecules?
Part of the assumptions set of an ideal gas is that there are no attractive or repulsive forces between them.

Also, part of the assumption is that the volume of molecules obtain a negligible amount when compared to the overall volume of the gas.
