An interactive simulation of water molecules as they form a solid, liquid, and gas. The user can add or remove heat from the system and watch the phase change, as well as changing the volume to model a pressure-temperature diagram. Key Concepts: Temperature, Phase Transitions, States of Matter, Molecular Interaction
An interactive model allowing the user to observe the relationship between phase change and kinetic/potential energies. The user can heat and cool helium, observing the exchange of energies. Key Concepts: Latent Heat, Temperature, Physical v. Chemical Changes
