  2. Why salt melts ice — and how to use it on your sidewalk - AOL

    www.aol.com/news/chemists-told-us-why-salt...

    Ice has a semi-liquid surface layer; When you mix salt onto that layer, it slowly lowers its melting point.. The more surface area salt can cover, the better the chances for melting ice.. Ice ...

  3. Mpemba effect - Wikipedia

    en.wikipedia.org/wiki/Mpemba_effect

    The phenomenon, when taken to mean "hot water freezes faster than cold", is difficult to reproduce or confirm because it is ill-defined. [4] Monwhea Jeng proposed a more precise wording: "There exists a set of initial parameters, and a pair of temperatures, such that given two bodies of water identical in these parameters, and differing only in initial uniform temperatures, the hot one will ...

  4. Brine rejection - Wikipedia

    en.wikipedia.org/wiki/Brine_rejection

    Once the ice reaches a critical thickness, roughly 15 cm, the concentration of salt ions in the liquid around the ice begins to increase, as leftover brine is rejected from the cells. [1] This increase is associated with the appearance of strong convective plumes, which flow from channels and within the ice and carry a significant salt flux.

  5. Snow removal - Wikipedia

    en.wikipedia.org/wiki/Snow_removal

    The salt, via freezing point depression, helps melt the snow and ice and also gives vehicles more traction. Later, usually when the snow has ceased falling, snow plows, front end loaders with snowplow attachments, and graders cover every street pushing snow to the side of the road. Salt trucks often then return to deal with any remaining ice ...

  6. Supercooling - Wikipedia

    en.wikipedia.org/wiki/Supercooling

    This is "pseudo-supercooling" because the phenomenon is the result of freezing point lowering caused by the presence of salt, not supercooling. This condition is most commonly observed in the oceans around Antarctica where melting of the undersides of ice shelves at high-pressure results in liquid melt-water that can be below the freezing ...

  7. The Easy Way to Melt Ice You Never Knew About (It’s Not Salt!)

    www.aol.com/easy-way-melt-ice-never-210537871.html

    While there are plenty of clever uses for salt, including fixing slippery surfaces, rock salt isn’t always easy to find once temperatures drop lower than the melting point of ice (32°F or 0°C).

  8. Snowmelt - Wikipedia

    en.wikipedia.org/wiki/Snowmelt

    In hydrology, snowmelt is surface runoff produced from melting snow. It can also be used to describe the period or season during which such runoff is produced. Water produced by snowmelt is an important part of the annual water cycle in many parts of the world, in some cases contributing high fractions of the annual runoff in a watershed.

  9. Brinicle - Wikipedia

    en.wikipedia.org/wiki/Brinicle

    A brinicle (brine icicle, also known as an ice stalactite) is a downward-growing hollow tube of ice enclosing a plume of descending brine that is formed beneath developing sea ice. As seawater freezes in the polar ocean, salt brine concentrates are expelled from the sea ice, creating a downward flow of dense, extremely cold, saline water , with ...
