Icebergs float on water because the underlying liquid water has a higher density than the iceberg. Liquid water itself has its highest density at 4°C—one of the so-called anomalies of water, i.e.

Liquids may seem simple, but on the molecular level, they are anything but. Molecules in a liquid are constantly in motion, shifting and reorganizing in complex ways. Understanding how molecules ...

These 10 – 30 second, unnarrated animations are chemically accurate representations of what's happening on the atomic level in some common chemistry outreach activities. Use them to help illustrate ...

The chaos typical of liquid molecules, and the ordering characteristics of crystals. There are states of matter connecting such contradictory features: liquid crystals. Thanks to an innovative ...

Consider the nearest water surface: a half-full glass on your desk, a puddle outside your window, or a lake across town. All of these surfaces represent liquid-vapor interfaces, where liquid meets air ...

Liquids and solutions may look simple, but on the molecular scale they are constantly shifting and reorganizing. When sugar dissolves in water, each sugar molecule quickly becomes surrounded by fast ...
