Can cryogenics freeze alcohol?!
Answers: If you put a litre of vodka in a plastic bag and froze it cryogenically (liquid nitrogen), would it become a solid? If so, when it left the frozen state (via natural defrosting, not heating), would it vaporize or return to a liquid? And how long would that take?
Liquid nitrogen will freeze alcohol solid...when returned to room temperature, it returns to a liquid state- it does not deliquesce.
why do you wanna know?
liquid.. just as long as a regular ice cube depending on climate
Maybe the Science Category (Chemistry) would be a better place to ask your question..=)

If liquid nitrogen gets down to -173F, then yes, it would freeze. Otherwise, it will simply be a thicker and thicker liquid as the temperature drops. If you thaw it back to room temperature (or any temperature above -173F, for that matter), it will be a liquid again. You'd have to heat it very rapidly to get it to sublimate.
Vodka has a freezingpoint of -36c, Liquiod nitro -170ish
crygenics is the study of things below absolute zero...
100% your alcohol will freeze and it will take a long time for it to defrost, depending on the temperature provided...
1. Yes.
2. It would return to a liquid state.
3. Assuming you let it defrost at room temperature, probably about an hour.
you don't need cryogenics for that. my freezer freezes every alcohol i put in there if i leave it for a couple weeks. stoli, absolute, yukon jack, smirnoff. i've never tried anything like everclear in there. that might not freeze so easily. it's not that alcohol doesn't freeze, it just needs a lower temp than water.
depends on the % of alcohol in the vodka. If it's low then the freezing temperature is going to be higher then that of pure alcohol which would be low like -114degree celcius. the temperature of liquid nitrogen at normal atm pressure is about -195.8degree celcius. so it is possible for it to freeze it. it depends how long it would take for it to defrost. what is the surrounding temperature? room temperature? sunny day? etc. these variables would effect defrosting rate
Yes, alcohol (vodka or whatever) has a freezing point, it's just lower than what you usually have access to, meaning that if you put it in your freezer, or a snowbank, it'll stay liquid, but get it cold enough it'll freeze like everything else.
If you did natural defrosting, it would return to liquid state. States are solids, liquids, gases. If you have to heat it normally to get it to a gas point, then just letting it defrost isn't going to magically turn it into gas.
As for how long it would take, that depends on how strong it was (how much alcohol) and how much you had, and how dense it was - a bottle thickness would take longer than a straw thickness, but not as much as a barrel thickness.
I believe it's one of the great mysteries of our time.
Anyone can freeze alcohol! Dry ice will do it as long as its not grain alcohol.
