Are Fizzing Drinks Boiling? A Chemical Insight from Chemical Education Research  Alan Goodwin
The suggestion that fizzing drinks are examples of liquids boiling at room temperature has proved to be controversial among both chemists and chemical educators. This paper presents a case for believing this everyday system to be a good example of a boiling solution and the consequent separation of carbon dioxide from the solution to exemplify fractional distillation.
