- A 2D interactive simulator demonstrates kinetic molecular theory using particles that move, collide, and respond to user-controlled parameters.
- Temperature is defined as the average kinetic energy per particle, directly controlled by a slider, with absolute zero corresponding to zero motion and pressure.
- Pressure is measured from particle collisions with walls, and it increases with higher temperature or smaller volume, illustrating gas laws like Boyle's and Gay-Lussac's.
- The Maxwell-Boltzmann speed distribution emerges from particle collisions, showing a range of speeds even at a fixed temperature, with a histogram displayed.
