Website: https://phet.colorado.edu/sims/html/states-of-matter/latest/states-of-matter_en.htmlOpen the PhET state of matter simulator.
Introduction: On the first tab (solids, liquids, and gases) click on each of the three states on the right: solid, liquid, and gas. For each state write your observations for what is happening in the space below.

What is the difference in the behavior of the particles between the three states of matter?
Hypothesis: How do you predict changing the temperature will affect the movement of the particles? The pressure?
Procedure:
Click on the phase change tab at the top.
Select neon on the right as your atom.
Drag the heat slider up to increase the temperature until it reaches 20 K. (You must hold it up to continue heating).
Wait 5 seconds for the pressure to catch up, and then record the pressure at 20 K in the chart below. The pressure will be constantly changing so estimate the closest whole number.
Repeat steps 3 and 4, increasing the temperature by 20 degrees each time and recording the approximate pressure in the chart below.
When this is complete, click reset all at the bottom.
Select water as your atom.
Drag the heat slider up to increase the temperature until it reaches 250 K. (You must hold it up to continue heating).
Wait 5 seconds for the pressure to catch up, and then record the pressure at 250 K in the chart below. The pressure will be constantly changing so estimate the closest whole number.
Repeat steps 8 and 9, increasing the temperature by 100 degrees each time and recording the approximate pressure in the chart below.
After completing these 2 trials, experiment on your own with the simulator and change the volume of the container by pushing the lid down or pulling it up. Attempt to determine how volume affects temperature and pressure.

Analysis and Conclusion:
How does temperature affect pressure?
At what approximate temperature did water become a liquid? A gas?
Why do you think water requires such a higher temperature to raise the pressure than neon?
How does volume affect temperature and pressure?
What conditions would produce the highest pressure?
How does the behavior of the particles determine the properties of the state of matter?
