Wife decided it was an evening for some lagers so picked up a box of Corona on the way home.
Not cold so put a good handful in the freezer to chivvy them along somewhat.
Got them out about an hour later. Properly cold and lovely but not frozen.
'put a slice of lemon in mine' came the command from her in charge, and which I dutifully did.
Then, right before my eyes, the whole body of liquid turned into a frozen slush puppy.
Never seen that before!
so, what gives?
magic?
maybe, but not a lot!
It's the beer god's wrath for ruining perfectly good beer by putting a slice of lemon in it 😆
Yeah, everyone knows it should've been a lime
superb youtuve find mate!
thanks for that - will pull that trick in the future!
I think the beer freezing has something to do with the CO2 in the beer coming out of solution and lowering the temperature of the beer (or raising its freezing point).
With the CO2 in solution the freezing point is lower than the temperature of the beer (liquid). So when the CO2 is encouraged out of solution, the freezing point changes to be above the temperature of the beer (solid). I think!
An unexpectedly dramatic effect. Very very cool.
I think this is due to [url= http://en.wikipedia.org/wiki/Raoult%27s_law ]Raoult's Law[/url]
Just for the record it's lime and not lemon you put in a bottle of corona and other mexican beer 🙂
Not sure if the lemaon was the cause, I've seen it often as the beer spends a couple of minutes at air temp and bosh, beer slush all over the place!
Adiabatic expansion- that is a drop in pressure (open the bottle) gives a drop in temperature (ice crystals forming)
