The curve is very steep physics.stackexchange.com/questions/60170/… The release of CO2 changes the freezing point somewhat, but more important is the heat release, not the change of the freezing point. | |

The release of pressure changes the temperature when water freezes. See the phase diagram for water. The release of $\ce {CO2}$ would increase the freezing point, not lower it. | |

| Oct 19, 2014 at 16:41 | comment | added | Dan | Its definitely still liquid, but it's starting to freeze slightly | |
| Oct 19, 2014 at 16:40 | comment | added | Brinn Belyea | Is the freezing in the beer, or is it on the outside of the can? | |

| Oct 19, 2014 at 16:40 | comment | added | Brinn Belyea | If the beer freezes as soon as you open it, then it is most likely a supercooled solution that froze upon being disturbed. If it takes time to freeze, it is most likely the loss of CO2 from the solution. | |

| Oct 19, 2014 at 16:37 | comment | added | Dan | Within a minute, ice that wasn't there initially has appeared on the can | |
