Each gas has its own partial pressure and gases move down their own partial pressure gradients. That's Dalton's Law, right? And Henry's the... Solubility. Boyle's Law states as an inverse relationship with the volume of a closed container and the pressure inside of that closed container. If you make it contain a larger, the pressure inside goes down. You make it smaller, the pressure goes up. It makes total sense because inside a box, there's X amount of gas particles. So they're more likely to bounce off the walls and bounce off each other. What kind of... To a dog park. Yes.
