The ideal gas law can be used to relate the volume at the surface to the submerged volume of the bubble. We assume the amount of gas in the bubble doesn’t change as it rises. The pressure at the submerged location is found from Eq. 13-6b. PV = nRT ! PV T = nR = constant ! P surface V surface T surface = P submerged V submerged T submerged !
