氣壓不同下的沸點換算(水)?

P = exp[20.386 - (5132K/T)]

from http://en.wikipedia.org/wiki/Vapour_pressure_of_water

lnP = 20.386 - 5132/T

ln(770) = 20.386 - 5132/T

6.6463905 - 20.386 = - 5132/T

-13.7396 = - 5132/T

T = 373.52K

= 100.52⁰C

如果用 Antoine equation
(同一個網頁 : http://en.wikipedia.org/wiki/Vapour_pressure_of_water )

會解得 100.21 ⁰C

據該網頁所言 :

Approximation formula[edit]

The vapour pressure of water may be approximated by the following relations (in order of increasing accuracy):

100.21 ⁰C 會是較準確結果。
