Answer (1 of 9): The boiling point of water is the temperature at which the vapour pressure of the liquid water equals the surrounding pressure. Methanol has a Boiling point of 64.7C (148.5 F; 337.8 K) Boiling Point of Milk The cow's milk's boiling point is about 203 F (95 C) Boiling Point of Alcohol The boiling points of alcohols of equal molecular weights are much higher than those of alkanes. The boiling point is the temperature at which a liquid substance changes to its gaseous phase. You can sometimes find them in a journal or in tables. The boiling point decreases as atmospheric pressure decreases, so it will be slightly lower than published values unless you are at sea level. The normal boiling point (also called the atmospheric boiling point or the atmospheric pressure boiling point ) of a liquid is the special case in which the vapor pressure of the liquid equals the defined atmospheric pressure at sea level, 1 atmosphere . 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. Flaming the liquid to burn off the alcohol still allowed for 75 percent retention. calculated and displayed (55.5 kJ/mol). In this article we shall study about the definition of boiling point.
