Boiling Point of Water in Nature
Like all liquids, water boils when its vapor pressure reaches its surrounding pressure. In nature, the atmospheric pressure is lower at higher elevations and water boils at a lower temperature. The boiling temperature of water for atmospheric pressures can be approximated by the Antoine equation:
or transformed into this temperature-explicit form:
where the temperature is the boiling point in degrees Celsius and the pressure is in Torr.

Famous quotes containing the words boiling, point, water and/or nature:
“Unmeasured power, incredible passion, enormous craft: no thought
apparent but burns darkly
Smothered with its own smoke in the human brain-vault: no thought
outside; a certain measure in phenomena:
The fountains of the boiling stars, the flowers on the foreland, the
ever-returning roses of dawn.”
—Robinson Jeffers (1887–1962)
“It used to be said that, socially speaking, Philadelphia asked who a person is, New York how much is he worth, and Boston what does he know. Nationally it has now become generally recognized that Boston Society has long cared even more than Philadelphia about the first point and has refined the asking of who a person is to the point of demanding to know who he was. Philadelphia asks about a man’s parents; Boston wants to know about his grandparents.”
—Cleveland Amory (b. 1917)
“Why are a lady’s thighs always cool? That is, said the monk, due to three causes for which a place is always naturally cool: primo, because water runs all the way down it; secondo, because it is in a shady, dark and obscure place, where the sun never shines; and thirdly, because it is continually fanned by the winds from the breezy hole.”
—François Rabelais (1494–1553)
“It is in the very nature of things human that every act that has once made its appearance and has been recorded in the history of mankind stays with mankind as a potentiality long after its actuality has become a thing of the past.”
—Hannah Arendt (1906–1975)
