What changes affect gases more than solids or liquids?
As gas is compressed, the spaces between the particles?
The lowest possible temperature at which particles no longer move is called?
Particles in matter _____ with walls of their container, creating pressure?
Gasses are affected by pressure changes more than solids or liquids. Part of that reason is because gasses have no definite volume. If you decrease the volume of space that a gas occupies, its pressure goes up. If you increase the space, the pressure goes down. That's Charles Law, and it does apply to one of your graph questions.
As a gas is compressed, the space between the particles gets smaller and smaller.
The lowest possible temperature at which particles no longer move is called absolute zero. It's not specific to gasses. Particles in all matter move at least a little bit. Absolute zero would stop all of that.
Particles in matter "bump into or push against" the walls of their container to create pressure.
