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.

The ultrafast placement of an electron in a polar liquid generates collective molecular vibrations in a spherical nano-volume. The vibrations change the diameter of this sphere periodically for more ...

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 ...

A new study provides strong evidence for a controversial theory that at very cold temperatures water can exist in two distinct liquid forms, one being less dense and more structured than the other.

Water is unique. It is one of the only substances that can exist in nature as a solid, liquid and gas at the same time under ambient conditions (think of solid ice over a pond, which is liquid ...

Water is clear and colorless and has many interesting and useful characteristics. There are other liquids that are also clear and colorless but have properties very different from water. In this ...

New research published in Nature reveals that, when cooled, droplets containing chain-like liquid crystal molecules transform from spheres into complex shapes such as flowers, corals, and fibrous ...

A team of physicists has pulled off a visual trick that sounds like stage magic: they made a flash of light vanish inside a ...

Water, so ordinary and so essential to life, acts in ways that are quite puzzling to scientists. For example, why is ice less dense than water, floating rather than sinking the way other liquids do ...
