High Altitude Cooking - Boiling Point of Pure Water at Elevated Altitudes

Boiling Point of Pure Water At Elevated Altitudes

Based on the standard sea-level atmospheric pressure of 1013.25 hPa:

Altitude, m Boiling point of water, °C
0 (0ft) 100 (212°F)
300 (984.25ft) 99.1 (210.3°F)
600 (1968.5ft) 98.1 (208.5°F)
1000 (3280.8ft) 96.8 (206.2°F)
2000 (6561.68ft) 93.3 (199.9°F)
4000 (13123.36ft) 87.3 (189.1°F)
6000 (19685.04ft) 81.3 (178.3°F)
8000 (26246.72ft) 75.5 (167.9°F)

With the addition of salt and other dissolved substances, the boiling temperature increases.

Famous quotes containing the words boiling, point, pure, water and/or elevated:

    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)

    Modernity exists in the form of a desire to wipe out whatever came earlier, in the hope of reaching at least a point that could be called a true present, a point of origin that marks a new departure.
    Paul De Man (1919–1983)

    who cooked rotten animals lung heart feet tailborscht & tortillas
    dreaming of the pure vegetable kingdom,
    Allen Ginsberg (b. 1926)

    What a dissimilarity we see in walking, swimming, and flying. And yet it is one and the same motion: it is just that the load- bearing capacity of the earth differs from that of the water, and that that of the water differs from that of the air! Thus we should also learn to fly as thinkers—and not imagine that we are thereby becoming idle dreamers!
    Friedrich Nietzsche (1844–1900)

    What is commonly honored with the name of Friendship is no very profound or powerful instinct. Men do not, after all, love their Friends greatly. I do not often see the farmers made seers and wise to the verge of insanity by their Friendship for one another. They are not often transfigured and translated by love in each other’s presence. I do not observe them purified, refined, and elevated by the love of a man.
    Henry David Thoreau (1817–1862)
