The particle model is the name for the diagrams used to draw solids, liquids and gases. In the model, the particles are shown as circles or spheres. However, the particles in ice, liquid water and ...

The liquid becomes a gas ... Brownian provides evidence for the kinetic particle model of matter. The microscopic particles that are observed in Brownian motion can be moved by collisions with ...

Students will be able to develop and explain a particle-level model to describe their observations of water dissolving salt, the water evaporating, and the salt crystals re-forming. Dissolving a solid ...

Students will be able to develop and explain a particle-level model to describe evaporation and condensation ... Evaporation happens when water molecules at the surface of a liquid move fast enough to ...
