Water boiling at 99.3 °C (210.8 °F) at 215 m (705 ft) elevation. The boiling point of a substance is the temperature at which the vapor pressure of a liquid equals the pressure surrounding the liquid [1] [2] and the liquid changes into a vapor. The boiling point of a liquid varies depending upon the surrounding environmental pressure.
This is a list of the various reported boiling points for the elements, with recommended values to be used elsewhere on Wikipedia. ... Celsius Fahrenheit; 1 H ...
At sea level, water boils at 100 °C (212 °F). For every 152.4-metre (500 ft) increase in elevation, water's boiling point is lowered by approximately 1°F. At 2,438.4 metres (8,000 ft) in elevation, water boils at just 92 °C (198 °F). Boiling as a cooking method must be adjusted or alternatives applied.

At the nominal body temperature of 37 °C (99 °F), water has a vapour pressure of 6.3 kilopascals (47 mmHg); which is to say, at an ambient pressure of 6.3 kilopascals (47 mmHg), the boiling point of water is 37 °C (99 °F). A pressure of 6.3 kPa—the Armstrong limit—is about 1/16 of the standard sea-level atmospheric pressure of 101.3 ...
In hydrothermal vents, the temperature can exceed 400 °C (752 °F). [67] At sea level, the boiling point of water is 100 °C (212 °F). As atmospheric pressure decreases with altitude, the boiling point decreases by 1 °C every 274 meters. High-altitude cooking takes longer than sea-level cooking.
This put the boiling and freezing points of water 180 degrees apart. [8] Therefore, a degree on the Fahrenheit scale was 1 ⁄ 180 of the interval between the freezing point and the boiling point. On the Celsius scale, the freezing and boiling points of water were originally defined to be 100 degrees apart.
