why there have bubble in beer,
what the pathway do the bubbles go in pv diagram


my idea :

assume temperature is constant
pressure in the bottom is higher than the suface
so the bubbles size increase

then where the energy come from????

is this action violate the first law of thermodynamics??
how about if you shake the beer, is it mean you input the energy into the system , then do it violate the 1st of thermodynamic?

Run a Google search on "carbonation" and "beer" and you will find out all you need to know about how these bubbles seem to appear from nowhere.
