Simulation Description: Particle model of matter, diffusion and compression
🧪 Particle Model Simulation — Description
An interactive canvas simulation covering the particle model. Three tabs:
- States — side-by-side solid, liquid and gas panels. Tap to select and see the correct particle arrangement for each state, with bond lines in the solid and continuous random motion in the liquid
- Heating — a single set of particles in a hex lattice that transform as you drag the thermometer: vibrating faster as a solid, breaking free into liquid flow at the melting point, then spreading rapidly as gas at the boiling point. Fire grows under the container as temperature rises
- Properties — drag a piston to compress gas particles into liquid then solid, or open a barrier to watch two gases diffuse and mix
Exit question: Why does the temperature stay the same during melting even though heat is still being added? (latent heat)
