3. Contraction The process of decreasing volume
Example: When a volume of gas gets cold, its volume decreases

4. Expansion The process of increasing volume
Example: When a volume of gas gets hot, its volume increases.

5. Compression When particles are forced into a smaller space.
Example: When you push the plunger in on a capped syringe filled with air.

6. Kinetic Energy Energy of motion
The speed at which a particle moves is directly related to the amount of kinetic energy it has.
