freezing bottle of beer?

Question

When I put a bottle of beer in the freezer and then pull it out before it has frozen, I find that the instant I open it it begans to freeze and starts to flow out of the bottle. Why??

Answer 1

The co2 is reacting to the ice in the bottle and also the beer will try to escape due to the pressure that has built up. When you freeze a liquid the molecules rush around and expand. If you were to leave it in the fridge it would break and cause a mess. Put a soda bottle almost full of water in the freezer with the cap on (mark the water level). When it reaches freezing you will hear the cap blow off the bottle and ice will be at the top of the bottle.

You can also try disrupting the co2 in your (or preferrably your friends) beer by tapping the top of the bottle hard enough to get it to spew over. (Just don't chip the bottle... glass is a btcih to drink.)

Answer 2

No more space for the beer to expand. The water in it is freezing. Leave it long enough in the freezer and the glass will shatter.

Answer 3

Because the carbon dioxide dissolved in the beer becomes free to escape. As it comes out of solution, the remaining liquid becomes denser, lowering its freezing point (think about how salt water will freeze more slowly than distilled water), and all that CO2 coming out of solution pushes the beer out of the bottle.

Answer 4

The beer is made mostly of water. When you put it in the freezer, the pressure changes and it causes it to foam up when you open it. I recommend only leaving a beer in the freezer unless you absolutly have to, or put in in the fridge for awhile after.

Answer 5

Oh yes! And it is NOT FUN to clean out of the freezer. I've accidentally done that way too many times at the restaurant when we've been running out of cold beer...and then I forget they're in there. Ooops!

Answer 6

The H2O can not freeze that well in glass .
