Carbonated drinks contain dissolved CO2. The solubility of gases is inversely proportional to temperature, therefore, at lower temperatures more CO2 is dissolved.
Carbonated beverages contain carbon dioxide gas, which is dissolved in water under high pressure. The gas remains dissolved in the drink until the drink can is opened, then it will be released in form of fizz and bubbles. Keeping carbonated drink cold is important because it enhances the continuous dissolution of carbon dioxide in the drink. This is because low temperature increases the dissolubility of gases in solvents.
