Gas pressure is caused by

• gas molecules colliding with surfaces
• gas molecules condensing to a liquid
• gas molecules hitting other gas molecule
• barometers

What is Diffusion?

• The movement of a substance from higher concentration to a lower concentration
• The passage of a gas through a tiny hole into an evacuated chamber

What is Effusion?

• The passage of a gas through a tiny hole into an evacuated chamber
• The movement of a substance from higher concentration to a lower concentration

Increased concentration of gas?

• fewer collisions, No change in means free path 
• More collisions, increase means free path
• More collisions, decreases means free path
