### water:

Carbonated water
* contains dissolved carbon dioxide gas.
* is called 'agua con gas' and still water is 'agua sin gas'
  - part of soda
* supersaturated solution of carbon dioxide gas in water.
+ Supersaturation, Examples: Chemistry :: Thermodynamics
  * Carbonated water is a supersaturated solution of carbon dioxide gas in water. At the start, the pressure in the bottle is very high. This means that more Carbon dioxide gas can be put into the water than at normal pressure. When the bottle is opened, the pressure falls to the normal level, and the carbon dioxide gas escapes very slowly. Certain things such as small bubbles in the bottle can make this process faster. Such bubbles can be caused by shaking the bottle.
