The boiling point at atmospheric pressure (14.7 psia, 1 bar absolute) for some common fluids and gases can be found from the table below: T (oF) = [T (oC)] (9/5) + 32 T (oC) = 5/9 [T (oF) - 32] Water Boiling Point vs. Altitude . However, at higher altitudes, hence lower pressures, like 2000 m above sea level, water boils at 98 C (208.4 F). This way the boiling point of the mixture also lowers down. One practical application of the different boiling points of alcohols and of alcohol with respect to water and other liquids is that it can be used to separate them using distillation. Methanol, CH3-OH, is a colorless, fairly volatile liquid with a faintly sweet pungent odor, similar, but somewhat milder and sweeter than ethanol. Namely that methanol has a vapour pressure of 1 atm precisely at this temperature - the liquid boils, and pushes back the atmospheric pressure, and bubbles of vapour form directly in the liquid. Usually, boiling points are published with respect to atmospheric pressure (101.325 kilopascals or 1 atm ). Boiling Points of Ethanol, Methanol, and Isopropyl Alcohol.
