Carbonation is the process of dissolving carbon dioxide gas (CO2) in a liquid, typically water. This creates bubbles and gives the liquid a fizzy texture. Carbonation occurs naturally in some mineral springs, but it can also be artificially added to beverages like soda and sparkling water. When a carbonated drink is opened, the pressure is released, allowing the gas to escape and form bubbles. This effervescence is what many people enjoy in drinks. The carbonation process can also affect the taste, making beverages feel more refreshing and enhancing their flavors.
