Why do your lungs expand, or get bigger, when you breath in? Discuss using Avogadro's Law.
Moles and Volume have a direct relationship therefore, increase volume you're also increasing moles. More air is going inside the lungs.

Describe what happens when two gas atoms collide together. (must discuss elastic collisions and total kinetic energy)
The two atoms collide and keep their own kinetic energy. This elastic collisions between the two atoms does not change the total kinetic energy.

A sample of oxygen gas is in a closed container. The gas and the container are at room temperature. According to the kinetic molecular theory of gases, what happens when a molecule of the gas collides with the container wall?
No energy is transferred between the molecule and the container.
