Abstract
A theoretical investigation on equilibrium conditions for a gas bubble immersed in a finite volume of liquid closed to mass transport discloses the possibility of thermodynamically stable states. The theory is verified by an experimental examination involving single gas bubbles of radii between 300 and 450 mu m contained in approximately 1.3 cc of a water-nitrogen solution at a temperature of 25.0 degrees and a pressure near 760.0 mmHg. An extension of the theory to the domain of microbubbles is carried out to propose a mechanism of their stability as observed by other investigators.
