why do carbonated drinks maintain their carbonation better when cool vs warm?

Question

**Example:** If I leave an opened carbonated drink out on the counter over night it will have gone flat by morning, but if I keep the same opened drink in the fridge over night it’s still holding the carbonation the next day

Answer 1

[CO2 stays in cold water better than warm water](https://en.wikipedia.org/wiki/Carbon_dioxide_%28data_page%29#Solubility_in_water_at_various_temperatures). Notice how lower temperatures have higher grams. Unlike salts or other solids, gasses tend to dissolve better in cold liquids. This is because the default reaction for a gas is (usually) to return to being a gas as opposed to salt’s default reaction being to dissolve, and the higher heat makes the default reaction happen easier.
