Where are the bubbles of the Pepsi in the bottom of the cup coming out???
Answers:
They come from CO2 that is held in solution in the liquid. This is known as carbonation.
Under pressure the liquid is able to hold more CO2 in solution. However, when you open the bottle and pour it in a glass the liquid is no longer under pressure so the CO2 comes out of solution and forms bubbles.
Released carbon dioxide out of the solution.
That question doesn't make any sense
