Setup section
2. Activity setup
Set up the simulation before collecting observations.

Phase Changes
1
Select Phase Changes.
2
Make sure Neon is selected.
3
Heat the neon to 40 K. K means Kelvin. 40 K is about -233 °C.
4
Let the simulation stabilize. Give it 4 minutes before beginning extra experiments.
Observation section
3. Time to make observations
Change one thing at a time. After each experiment, reset and return to 40 K before testing the next variable. Do the experiment to the point you see a clear change.
Experiment 1: Decrease volume
Watch the pressure reading while the volume gets much smaller. Push the wall far enough that the container is clearly compressed, not just slightly nudged.
Experiment 2: Add more heat
Reset the experiment, heat back to 40 K, and let it stabilize first. Then add enough heat that the temperature and pressure readings clearly change.
Experiment 3: Add molecules
Reset first. Use the pump at least 50 times so the pattern is easier to see.
Reset the experiment and reheat back to 40 K before starting each new test. Give it 4 minutes to stabilize.
Pattern section
4. Choose the pattern that matches what you observed
For each variable, choose what happens to pressure, the graph that matches the pattern, the type of relationship, and the formula form.
Quick relationship guide
Directly proportionalBoth variables move in the same direction. If one increases, the other also increases.
Inversely proportionalThe variables move in opposite directions. If one increases, the other decreases.
ConstantOne variable changes, but the other stays the same.
LinearThe graph is a straight line. A direct proportion is a special kind of linear relationship that goes through the origin.
