Cargo temperatures vary in our fleet. The Boeing 767 maintains its baggage hold above 7˚C, but the bulk area (where animals are carried) can be heated above 18˚C. “Controlled temperature cargo bins are also available when temperature-sensitive goods are being shipped.” I am wrong I admit but it could be down to temperature as opposed to pressure. Stick it in your pocket is all I can advise. The boiling point of alcohol depends on which type of alcohol you're using, as well as the atmospheric pressure. The boiling point decreases as atmospheric pressure decreases, so it will be slightly lower unless you are at sea level. Here is a look at the boiling point of different types of alcohol. The boiling point of ethanol or grain alcohol (C2H5OH) at atmospheric pressure (14.7 psia, 1 bar absolute) is 173.1 F (78.37 C). Methanol (methyl alcohol, wood alcohol): 66°C or 151°F Isopropyl Alcohol (isopropanol): 80.3°C or 177°F I know am not crazy.
