It turns out that depending on the pressure, water or any other liquid has different boiling points. In vaccum the boiling point of Ethanol reduces because the ambient pressure decreases. Alcohol is the hydroxyl group name given to the carbon compounds that end with -OH. The boiling point of ethanol or grain alcohol (C 2 H 5 OH) at atmospheric pressure (14.7 psia, 1 bar absolute) is 173.1 F (78.37 C). This is because of the fact that ambient pressure reduces. We shall discuss the reasons in detail in the section given below. Now you can calculate its boiling point under any pressure. If we consider only the blood, it does boil in vacuum at a faster rate. In a closed container or system, this means that the amount of molecules transitioning from a liquid state into a gaseous state is the same number as those going reverting back into a liquid after being a gas.
