Name __________________________Hr______ 2. How does Temperature affect pressure with set particles? Hot:

3. How does Volume affect pressure with set particles? Large:

Cold:

Small:

5. Give a definition for pressure:

6. How does the number of particles affect pressure with set volume? A lot: A little:

7. If you add particles to a container what would the before & after picture look like? Before

After

8. In terms of kinetic-molecular theory (gas particles) explain what happens when you add moles of a gas to: a) Metal air tank

b) Thin balloon

9. Create a concept map to illustrate how the pressure of a contained gas changes when the amount of gas and the size of the container are changed. It should have the following words / phrases: Adding Gas, Removing Gas, Increasing volume, Decreasing volume, Increasing gas pressure, Decreasing gas pressure, Increase temperature, Decreasing temperature.

Gas Pressure
