Freezing Point of Alcohol

The freezing point of alcohol and water mixture is therefore dependent upon the amount of alcohol per volume That is called the proof of alcohol The equation is something like this - the lower the proof the warmer is the freezing point and the higher the proof the lower and colder is the freezing point For instance 84 proof liquor freezes at -30 degree Fahrenheit while 24 proof liquor freezes at 20 degree

Freezing and Melting Points for common Liquids

Freezing point - the temperature at which a liquid turns into a solid The melting and freezing point changes with pressure but normally they are given at 1 atm A pure substance has the same freezing and melting points (in practice a small difference between these quantities can be observed) For mixtures of compounds (as petroleum) there are ranges of melting and freezing points versus

The Freezing Point of Alcoholic Drinks

In general it can be said that the more alcohol a drink contains the lower its freezing point The freezing point of water is at 32F (0C) while the freezing point of ethanol (the alcohol we drink) is at -173 4F (-114 1C) Since alcoholic drinks are mostly a mixture of water and ethanol the freezing point can be derived by the alcohol content in the mixture
