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.

“That devilish Iron Horse, whose ear-rending neigh is heard throughout the town, has muddied the Boiling Spring with his foot, and he it is that has browsed off all the woods on Walden shore, that Trojan horse, with a thousand men in his belly, introduced by mercenary Greeks! Where is the country’s champion, the Moore of Moore Hall, to meet him at the Deep Cut and thrust an avenging lance between the ribs of the bloated pest?”
—Henry David Thoreau (1817–1862)
“If mothers are told to do this or that or the other,... they lose touch with their own ability to act.... Only too easily they feel incompetent. If they must look up everything in a book, they are always too late even when they do the right things, because the right things have to be done immediately. It is only possible to act at exactly the right point when the action is intuitive or by instinct, as we say. The mind can be brought to bear on the problem afterwards.”
—D.W. Winnicott (20th century)
“The clock runs down
timeless and still.
The days and nights turn hours to years
and water in a gutter marks the circle of another world
hating, resentful, and afraid
stagnant, and green, and full of slimy things.”
—Margaret Abigail Walker (b. 1915)
“A painter told me that nobody could draw a tree without in some sort becoming a tree; or draw a child by studying the outlines of its forms merely,—but by watching for a time his motions and plays, the painter enters into his nature and can then draw him at will in every attitude.”
—Ralph Waldo Emerson (1803–1882)
