Does carbon dioxide help coca cola freeze?

Carbon dioxide does not directly help Coca-Cola freeze; instead, it contributes to the drink's carbonation. When Coca-Cola is frozen, the water content in the beverage turns to ice, while the carbon dioxide remains dissolved until the pressure is released. As the drink freezes, the expansion of ice can cause the container to crack or burst, especially if it's a sealed can or bottle. Therefore, while CO2 is present, it is not a factor that aids in the freezing process itself.
