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.
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 ...
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 ...
Scientists have discovered some unexpected forms of liquid crystals of ultrashort DNA molecules immersed in water, providing a new scenario for a key step in the emergence of life on Earth. A team led ...
A team of physicists has pulled off a visual trick that sounds like stage magic: they made a flash of light vanish inside a ...
