What happens to fizzy drinks in the refrigerator?

When a fizzy drink is placed in the refrigerator, the solubility of the dissolved gas in the liquid increases, causing more gas to dissolve and the drink to become less fizzy. As the temperature drops, the kinetic energy of the gas molecules decreases, which slows down their movement and makes them more likely to be trapped in the liquid. Additionally, the decrease in temperature causes the liquid to become more dense, which further increases the solubility of the gas. As a result, the drink becomes less fizzy and may even go completely flat if left in the refrigerator for too long.
