Why does cooling a can of fizzy drink before it is opened reduce the amount of bubbles produced?
Gases, like the carbon dioxide that makes drinks fizzy, are more soluble in liquids at lower temperatures. This can sound counter-intuitive since many other substances are more soluble at higher temperatures. So, cooling the drink makes the CO2 more soluble, thus reducing the amount of bubbles. It isn’t really counter-intuitive. Gases, like CO2, are rapidly-moving, light, molecules. As temperature increases their kinetic energy increases, allowing them to more easily escape a liquid in which they are dissolved.
