The simulation can be run in a browser. If you have issues with the simulation, try using another browser. If you are unable to run the simulation, your TA will provide you with remote assistance. When you run the simulation, choose the “Energy” option. At the very bottom of the screen you will see the other options for the simulation, including a home button, “Ideal,” “Explore,” “Energy,” and “Diffusion.” If you accidentally navigate to another area, you can return to the Energy option by clicking the button. The simulation shows a preset volume. In its initial configuration the box is empty. On the right side of the screen there is a menu labelled “Particles.” By expanding this menu, you can choose to add so many heavy or light particles. These particles will enter the volume at a temperature of 300 K in the initial setup. Once there are particles in the box, the temperature and pressure in the box can be read off the scales on the right corner of the box. The units can be changed for these values. To adjust the temperature of the particles in the box, move and hold the slider bar below the box. To the left of the box is a graph showing the speed of the particles. This is a histogram. By clicking the blue and red boxes below the graph, you can see the distributions of the heavy and light particles, respectively. The box above this shows the average speed of the heavy and light particles. Below the speed distribution graph is a menu that can be expanded to show the kinetic energy distribution of the particles. Again, by clicking the blue and red boxes below the graph, you can see the distributions of the heavy and light particles, respectively. On the left there is a handle to change the size of the box. There is also a lever at the top of the box that can be lifted to open the box, allowing particles to escape. Particles can also be removed from the box by reducing the number of particles in the “Particles” menu. Finally, to refresh the simulation to the initial point, click the arrow in the bottom right. https://phet.colorado.edu/en/contributions/view/3687 https://phet.colorado.edu/sims/html/gas-properties/latest/gas-properties_en.html Lab: The Maxwell-Boltzmann Distribution* Phys 242 2 I.
