Video of superheated water in a microwave explosively flash boiling, why it happens, and why it's dangerous. Bloomfield, Louis A. "A series of superheated water with oil film experiments done in the microwave by Louis A. Bloomfield, physics professor at the University of Virginia.
Pressure cookers produce superheated water, which cooks the food more rapidly than boiling water. Superheated water is liquid water under pressure at temperatures between the usual boiling point, 100 °C (212 °F) and the critical temperature, 374 °C (705 °F). [citation needed] It is also known as "subcritical water" or "pressurized hot water".
Boiling water, steam, mud, and rock fragments are ejected over an area of a few meters up to several kilometers in diameter. Although the energy originally comes from a deep igneous source, this energy is transferred to the surface by circulating meteoric water or mixtures of meteoric and magmatic water rather than by magma , as occurs in ...
The water changes from a solid or liquid to a gas with extreme speed, increasing dramatically in volume. A steam explosion sprays steam and boiling-hot water and the hot medium that heated it in all directions (if not otherwise confined, e.g. by the walls of a container), creating a danger of scalding and burning.

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.
An animal-lover in Chicago has helped a cat that was doused with boiling water in a Facebook video and is now receiving medical treatment. Cat gets doused with boiling water in viral video, man ...
Scalding is a type of thermal burn caused by boiling water and steam, commonly suffered by children. Scalds are commonly caused by accidental spilling of hot liquids, having water temperature too high for baths and showers, steam from boiling water or heated food, or getting splattered by hot cooking oil.
