Shaking the can produces tiny bubbles which serve as nucleation points for the dissolved CO2 to change phase into gaseous CO2. This increases the pressure . You have two phases in the can – liquid and a small amount of gas. By shaking it, you are forcing more CO2 into the gaseous phase.

Is shaking a soda can a chemical reaction?

However, producing foaming carbon dioxide gas by shaking a bottle of soda water is a physical change, while producing foaming carbon dioxide gas by combining baking soda and vinegar is a chemical change. Because no chemical bonds are broken and no new molecules are formed, this is a physical change in the system.

Answer 1: The bubbles in soda come from a gas called carbon dioxide that is dissolved into the soda . Only the bubbles at the top get to escape. Shaking a bottle of soda mixes up all the bubbles from the surface and they get distributed all throughout the soda and stick to the sides of the bottle as well.

How do you measure fizz in soda?

Remove the cap from the bottle of soda to be tested and quickly put the modified cap onto the bottle. The gas escaping from the soda should travel down the tube and into the glass jar.
