States of Matter Solid, Liquid, Gas: Computer animations

Computer animations representing what occurs at the particle level for solid, liquid and gas phases of matter

Purdue University

Freezing  (liquid and solid phases)  Does not show the equilibrium event between the two phases.

Boiling   Representation of what occurs inside the bubbles formed in water as it boils. Does show the equilibrium event between liquid and gas, two phases of matter, however this is within the "bubble".  This animation does not show what occurs at the surface of liquid water as it boils, the interface between the liquid phase and the gas phase.

Vapor Pressure   Does not show the equilibrium event between the two phases.

Condensation and Evaporation   Does not show the equilibrium event between the two phases.

Solid, Liquid, and Gas states of matter for Neon, Argon, Oxygen, Water at the Particulate Level of Matter: A computer Simulation

PhET  "Physics Education Technology," University of Colorado - Boulder

Does show a simple mathematical based model (computer simulation) of the three states of matter as represented by a cluster of atoms or molecules and a simple view of the transition states between the phases of matter: melting, boiling, condensation, freezing.  The vibration and movement of the atoms and molecules are not 100% "realistic" or "accurate", but does convey a good general representation of the states of matter, especially for young students."Physics Education Technology,"
