'Do not do demos unless you are an experienced chemist!' Please read the following disclaimer carefullyД«y continuing to view the descriptions of the demonstrations you have agreed to the following disclaimer. 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. PhET 'Physics Education Technology,' University of Colorado - BoulderДoes 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. Solid, Liquid, and Gas states of matter for Neon, Argon, Oxygen, Water at the Particulate Level of Matter: A computer Simulation

Vapor Pressure Does not show the equilibrium event between the two phases.Д¬ondensation and Evaporation Does not show the equilibrium event between the two phases.

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. Does show the equilibrium event between liquid and gas, two phases of matter, however this is within the 'bubble'. Computer animations representing what occurs at the particle level for solid, liquid and gas phases of matterДЇreezing (liquid and solid phases) Does not show the equilibrium event between the two phases.Д«oiling Representation of what occurs inside the bubbles formed in water as it boils.
