As a carbonated drink, such as soda, is heated, what happens to the solubility of carbon dioxide gas in the drink?

Answer 1

Most gases have less solubility as the temperature of the liquid solute increases. Wouldn't that make sense to you? You know that if you leave an opened carbonated drink on the table for several minutes that it goes flat. That's because the temperature of the cold drink increases, the CO2 bubbles out (you can see that happening) and soon there is almost no CO2 left and the drink tastes flat.
