Question

A bottle of beer was placed in a wine chiller of a fridge to cool.
Upon taking it out, opened the cap and stirred, the liquid beer immediately freezes. However, when the bottle of wine is overturned, it flows out as a liquid again.



Provide a scientific explanation for the above phenomenon

Answer 1

Beer is carbonated, wine is not.

A closed bottle of beer does not freeze at a temperature above -10C due to the dissolved gas (CO2) in the solution. The greater the number of solute particles, the lower the freezing point of the solution. The chemical nature of the solute does not influence the degree to which the freezing point is lowered, the number of dissolved particles does.

Now, open the wine and the beer. The beer freezes and the wine does not. What happens when you opened the beer? Carbon dioxide quickly escapes (the ssst sound you hear when you open the beer). The concentration of the CO2 in the beer is lowered - less solute molecules dissolved. The lowered concentration of CO2 results in less of a freezing point depression, and the solution will freeze at a higher temperature - instant beer slushie.

This does not happen in the case of the wine since the dissolved particles in the wine remain more or less constant after opening the bottle.

Answer 2

This is an example of freezing point depression that arises from adding a foreign object into the solution.

Wines have 5 - 11 % ethanol by volume; beers have 3.5 - 5% ethanol by volume. It is likely in this example the beer has less ethanol and ethanol is the foreign object causing freeze point depression. Therefore, with less ethanol in beer it freezes at a warmer temperature than the wine does.

Check out freezing point depression for more information. By the way, this is why you put commercial anti-freeze in your car's cooling system, it depresses the freeze point of the water.

Answer 3

Some wonderful points from the colligitave proporties are mentioned below. I'll also add that the ethanol content in the two solutions differs and Ethanol also decreases the freezing point.
