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:
“O but we talked at large before
The sixteen men were shot,
But who can talk of give and take,
What should be and what not
While those dead men are loitering there
To stir the boiling pot?”
—William Butler Yeats (1865–1939)
“I have proceeded ... to prevent the lapse from ... the point of blending between wakefulness and sleep.... Not ... that I can render the point more than a point—but that I can startle myself ... into wakefulness—and thus transfer the point ... into the realm of Memory—convey its impressions,... to a situation where ... I can survey them with the eye of analysis.”
—Edgar Allan Poe (1809–1849)
“Thales claimed that everything was water. He also put wine into water to sterilize it. Did he really believe he was putting water into water to sterilize it? Parmenides, like most Greeks, knew that wine was not water. But while lifting a glass of wine to his lips, he denied that motion was possible. Did he really believe that the glass was not moving when he lifted it?”
—Avrum Stroll (b. 1921)
“Our ancestors ... possessed a right, which nature has given to all men, of departing from the country in which chance, not choice has placed them.”
—Thomas Jefferson (1743–1826)
