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 ...
Cold water does not boil faster. Water boils when it reaches its boiling point of 212 degrees Fahrenheit, 100 degrees Celsius or 373 degrees Kelvin.
The boiling point of water is 100 °C or 212 °F but is lower with the decreased atmospheric pressure found at higher altitudes. Boiling water is used as a method of making it potable by killing microbes and viruses that may be present. The sensitivity of different micro-organisms to heat varies, but if water is held at 100 °C (212 °F) for ...
Leidenfrost droplet Demonstration of the Leidenfrost effect Leidenfrost effect of a single drop of water. The Leidenfrost effect is a physical phenomenon in which a liquid, close to a solid surface of another body that is significantly hotter than the liquid's boiling point, produces an insulating vapor layer that keeps the liquid from boiling rapidly.

A liquid in a partial vacuum, i.e., under a lower pressure, has a lower boiling point than when that liquid is at atmospheric pressure. Because of this, water boils at 100°C (or with scientific precision: 99.97 °C (211.95 °F)) under standard pressure at sea level, but at 93.4 °C (200.1 °F) at 1,905 metres (6,250 ft) [3] altitude.
This is because steam at 100°C has much more internal energy than water and can transfer it to the food faster through the agitation of a rolling boil. 203.27.72.5 01:08, 21 June 2012 (UTC) Keep in mind that a given volume of pure water actually contains more H 2 O than the same volume of salt water. Because salt water is an imperfect mixture ...
The warm, aromatic steam from chicken soup may also help loosen nasal mucus even more effectively than sipping on plain hot water. Plus, it’s a powerhouse of nutrients — protein from the ...
