- Water (main ingredient): Approximately 100 degrees Celsius (212 degrees Fahrenheit) at sea level.
- Sugar: Decomposes rather than boiling at around 160-180 degrees Celsius (320-356 degrees Fahrenheit).
- Caffeine: Sublimates rather than boiling at around 178 degrees Celsius (352 degrees Fahrenheit).
- Carbon dioxide (present in the carbonated version of Coca-Cola): Changes directly from liquid to gas at around -78 degrees Celsius (-108 degrees Fahrenheit).
- Other flavoring ingredients: Have varying boiling points, generally ranging from around 100 degrees Celsius (212 degrees Fahrenheit) to over 200 degrees Celsius (392 degrees Fahrenheit).
When heated, the more volatile components of Coca-Cola, such as carbon dioxide, will vaporize first, followed by water and other substances with higher boiling points. The exact temperature at which Coca-Cola starts to boil and the range over which it boils will depend on various factors, such as the altitude and the specific composition of the beverage.
