ELI5: How does the Carbon Dioxide in carbonated drinks stay in the liquid? (As opposed to all escaping at once)
gpt
The gas molecules grab onto the molecules in the water. It makes carbonic acid, and while the drink is cold, the bonds hold together and less gas escapes. 

When the drink gets warm, the bonds become less stable, and the carbon dioxide leaks back into the air. The carbonic acid then turns to water and carbon dioxide. 

That's why warm soda gets flat, and tastes sweeter. The carbonic acid mellows the sweet flavors.
