It doesn't.
Because of the high concentration of alcohol, 45% at 90 proof, the alcohol acts like an anti-freeze.
90 proof means the alcohol content is 45%, by volume.200 proof = 100%180 proof = 90%and so on.
The strongest alcoholic drinks can have alcohol content ranging from 40% to over 90%. However, many commercially available strong alcoholic beverages like spirits typically range from 40-50% alcohol by volume (ABV).
The answer varies in each different liquor, and should be listed on the bottle as "proof". The "Proof" is twice the alcohol percentage, so 40 proof is 20% alcohol, 180 proof is 90% alcohol.
90 proof = 45 % alcohol. A very strong drink indeed.
Everclear is listed at 180 proof, or 90% alcohol per vol.
well alcohol has a lower freezing temperature than water. Therefore it can go below 0 degrees celsius or 32 Fahrenheit and still be liquid. (Well for harder liquor anyways--not beer, it will freeze) But i think it will still be fine.
45% The percentage of alcohol is always 1/2 of the proof.
In general, whiskeys are at that level. But there are specific brands that dilute to 45%, Skyy 90 vodka comes to mind.
Yes, if the alcohol has a high enough alcohol has around a 90% potency (180 proof), some times way less can also do good, like a 50% (100 proof) can be effective to disaffectent a wound.
45%, or 90 proof 45%, or 90 proof Actually it is 50% alcohol by volume which makes it 100 proof. The Red Labeled bottle is 40% alcohol by volume making it 80 proof
Ammonia (Damages copper/brass fittings) and alcohol mix well in water. Imagine your Urea in a toilet and alcohol and brake fluid (water rusts brake components, replace brake fluid regularly) is hygroscopic which "sucks" attracts moisture out of the air surrounding these fluids. Alcohol is impossible to remove all moisture completely. This is the reason 99.9% alcohol fluids is the strongest concentration you can buy and listed as a damaging solvent. 40 proof or 20% alcohol in hard liquor is average. 30% ethanol by weight (60% proof) should freeze at -20°C. Your 90 proof spirits (45% by weight) would freeze at about -30°C. 25oz alcohol to one gallon water protects from freezing -5 F / -20C
