So what happens to volume? Well, according to Charles Law, this guy states that if we go outside and my temperature drops, then my volume must drop as well to make sure that our constant stays the same. That means if I go outside with my balloon, my balloon will shrivel, it will become smaller, and that's because of Charles Law. So once again, we see how macro scale events are explained by Charles Law, just like they were explained by Boyle's Law. So we have yet another law that helps us explain how gas molecules behave when we have a lot of them together, not simply individual gas molecules. Now, we can, of course, explain how Charles Law functions on an individual level using the kinetic theory.
