In Run mode, the Ultrascope View shows the motions of particles, the collisions between them, and the collisions between the particles and the container walls. Particles of different types of gases are depicted as different colors. The number of particles in the view changes according to variations in density. In Stop mode, the view shows only motionless particles. At the hotspots indicated below, you can attach meters for particle number density, average impulse per collision, and average particle speed or energy. To attach a meter, you must click directly on the hotspot, as indicated by the cursor below.
