Science Alive: Melting Point Simulation
Percy Julian and Josef Pikl used the fact that melting point-the temperature at which a substance changes from a solid to a liquid-is a characteristic property of a substance to prove that the British chemist Robert Robinson could not...
Purdue University
Purdue Univ: Gases, Liquids, and Solids
This site has a brief description of the differences in particles in a gas, liquid, and solid. Animated microscopic pictures demonstrate the molecular movement in each state. Information is then summarized in an easy-to-read chart.
