What has more fizz a warm coke or cold coke?

Here's why:

* Solubility of CO2: Carbon dioxide (CO2), the gas that creates the fizz in soda, is more soluble in cold liquids than in warm liquids.

* Pressure: When a soda is bottled or canned, it's pressurized with CO2. The lower temperature of a cold soda helps retain the CO2 under pressure.

* Evaporation: As the temperature of a soda increases, the CO2 molecules have more energy and are more likely to escape into the air, reducing the fizz.

In summary: The colder the Coke, the more dissolved CO2 it can hold, resulting in more fizz.
