1. To assess the role of temperature on movement of molecules, you can use this simulation here: https://phet.colorado.edu/sims/html/diffusion/latest/diffusion_en.html

• Start with 50 blue particles, set the temperature to 50K, check the box for center of mass and stop watch. The particles should be moving on the left side. Now click on remove the divider and click on the play button on the stopwatch function. Stop the watch once the blue bar on the bottom stabilizes on the dashed line in the middle. Note what the time is.
• Click on replace the divider and reset the stop watch by clicking on the arrow button.
• Now adjust the temperature to 500K, click remove the divider and start the stop watch. Stop the watch once the blue bar on the bottom stabilizes on the dashed line in the middle. Note what the time is.
