1. The problem statement, all variables and given/known data

Its not to calculate, actually, I am just trying to understand this. I think it has to do with Archimedes Principle, but could anyone explain the following more clearer to me?

"Its observed that as bubbles rise in a deep column of water, the diameter of the bubbles increases."

2. Relevant equations

3. The attempt at a solution

Re: Archimedes

I don't think it's particularly related to Archimedes' principle. Instead, think of the bubble as being an ideal gas. How are pressure and volume related? How does pressure in the fluid change as the bubble rises?

Re: Archimedes

does it have to do with Pascal`s then?

Re: Archimedes

Not especially. It has to do with static pressure in a fluid. What does it depend on?
