And therefore, they will all drop to the bottom of the container and they will collect and get very close. And if they're close, that means they're feeling electrostatic forces. And so our kinetic theory also breaks down on the low temperatures. Now let's compare the pressure of ideal and real systems. Now, for the pressure of an ideal system, remember they're not feeling electrostatic forces and that means they hit the wall of the container and they're not attracted or repelled by other molecules. For real situations, for real gases, the pressure is less.
