Re: [APD] Science

I did some reading and found an interesting tidbit that may add to the

The diffusion of gas from  the bubble into a region of liquid surrounding
the bubble is very fast.

The further diffusion of gas into the bulk liquid (from the high
concentration liquid surrounding the bubble) is slower - a rate limiting
step in the whole process.

So - if bubbles are near plants they will have regions of water about that
are much more concentrated in CO2 than the liquid as a whole.  Perhaps these
very saturated regions near the leaves which leads to happy plants.
