Gas bubbles are a chemical change. A common example can be soda. The bubbles in the soda are carbon, thus soda is carbonated, when you leave soda open and out in the open the carbon reacts with the oxygen in the air and forms carbon dioxide. Since there is a new chemical composition of the soda since it has lost carbon, also know as going flat, this is a chemical change. The above example is incorrect. The bubbles coming out of soda is not carbon reacting with oxygen;the bubbles are already carbon dioxide. Does pencil lead react with oxygen? The carbon dioxide in your soda is dissolved in solution. Gas bubbles in most other situations though ARE a sign of a chemical change.
CO2. Carbon dioxide.
It is a change in physical state, which is a physical change.
Frozen carbon dioxide is still carbon dioxide, so it is a physical change.
Nope. The pressure keeps the Carbon Dioxide dissolved in the liquid, and when that pressure is relieved, the CO2 rapidly returns to its gaseous state. None of the molecules are reacting or changing, although the CO2 switches from aqueous to gaseous phase.
the carbon dioxide dissolved in the drinks gives it its bubbles
The carbon dioxide bubbles from a chemical reaction.
Bubbles in refreshing drinks have three origins: 1. Fermentation of sugars: a chemical process 2. Dissolving of air from the atmosphere after a vigourous stirring: a physical process 3. Adding carbon dioxide under pressure: a physical process
Not always but they can. They may simply be an indication of a phase change, as when water boils. This is usually counted as a physical change rather than a chemical change. But if you add baking soda to vinegar, you will see bubbles as a result of a chemical change.

The pop that results is caused by the release of carbon dioxide bubbles that are encapsulated within the candy. This is a physical change, rather than a chemical reaction, because no new products are formed.
If you ae talking bubbles released from a can of soda = physical. It is just carbon dioxide being released. If you are talking bubbles produced from a mixture of baking soda and vinegar = chemical. It is actually changing the chemical composition and releasing oxygen from the H2O.
CO2 is a chemical symbol for the compound known as carbon dioxide. Carbon dioxide is those bubbles dissolved in your soda pop.
CO2. Carbon dioxide.
i think it is chemical but it may be physical.
When water and baking soda are stirred together, bubbles will form. These bubbles are carbon dioxide.
