Directions:
1. Google Phet states of matter or find the link on Google
Classroom
2. Click on States of Matter: Basics – PhET
3. Click on the second box: Phase Changes
4. Take a couple minutes to get to know the simulation.
5. Click on Neon.
6. Reset the simulation so you are starting at a pressure of
0.0 atm.
7. What are all the ways you can change the
pressure of this closed system? Share with your group.
8. What are the particles doing to cause the
pressure to increase (go up)? Share with your group.
9. Try to make the lid pop of the container.
Why did the lid pop off? Share with your group.
Reset the PhET by clicking the orange circular arrow
KEEP IN MIND: Your focus is how the PARTICLES are affecting the PRESSURE of the closed system.
Closed System: Nothing can get in or out. The container is a closed system in this PhET.
