Boiling
- For a discussion of the phenomenon of boiling in physics, see Boiling point.
Under special conditions, a liquid heated may show boiling delay when heated over its boiling point, by starting to boil suddenly and violently.
In places where the available water supply is contaminated with disease-causing bacteria, boiling water (and allowing it to cool) before drinking it is a valuable health measure. Boiling water for a few minutes kills most bacteria, amoebas, and other microbial pathogens. It thus can help prevent cholera, dysentery, and other diseases caused by these organisms.
