2. 12/1/15 Entry Task In your lab group come up with a definition of pressure. Everyone write down the group’s definition! Be prepared to share. ** Turn in Thermal Expansion Lab Sheet and Conclusion

3. 12/1/15 Gas Pressure Notes What will happen when the particle hit the wall of the container? As the particles of the gas collide with the container, they will exert a force on the container. The average force per unit of area is the average pressure of gas.

4. Pressure force acts perpendicular to the container.

5. If the volume of gas in a container is halved then the number of collisions with the wall doubles. Therefore, the pressure in container b is twice that of container a.

7. Peeps in a vacuum chamber https://www.youtube.com/watch?v=fxLY1SGXV_E Initial ideas on white board: Why did the peeps expand when you removed the air from the bell jar? Include 3 particle diagrams: at the beginning, after all the air was pumped out of the chamber after the air was let back into the chamber.
