This spiderman shot, deliciously amazing.
So, you're have friends over for a party and you pick up some beer and because you're gonna get lit right.
Unfortunately you can only get warm beer and you only like cold beer so you put it in the freezer an hour before the party.
You take one out and gently shake it to make sure they are not frozen. Luckily they are cold and not frozen! YAYYY
You open the can in your hand and IT INSTANTLY FREEZES!!!!!
WHY?
WHY DID THIS HAPPEN?
You may have experienced this with many different types of liquids, or even seen the Facebook videos. . .
So from a chemist's point-of-view. . .
Inside the beer there is what is considered to be an "impurity", which lowers the freezing point(Think 0 degrees to -7 degrees), essentially making the temperature it must be to freeze even less. The gas inside beer and many other sodas/pops is what we consider to be the impurity. Essentially, it just has to be even colder to freeze the liquid in the unopened can which contains the impurities. The liquid inside the can is cooled to the temperature of inside the freezer, and when opening the can, some of the impurities are released, causing the beer to instantly freeze, because now the freezing point has been raised(from -7 degrees to 0 degrees), meaning it does not have to be as cold to freeze. Essentially he liquid beer and the gas have different freezing points. The liquid does not have to be as cold to freeze as the liquid with the impurities.
It really has to do with freezing points of solvents and solutes in the solution.
*degrees are not accurate of actual temperature, and are just used for explanation purposes.
Moral of Story:
Don't leave it in the freezer for too long
Get drunk and lit
