It can be defined as the foam of air bubbles in aliquid medium in a stable dispersion. If the general air into the liquid, thebubble generated can assume a spherical shape. Since the air is lessdense than the liquid, and thus it will migrate to the surface, when the gasreaches the surface of the liquid without surfactant, the bubble will burst,the air inside the bubble dissipates, the liquid surrounding the bubble in theprevious and together. Thus, the pure liquid (liquid containing nosurfactant) there is no bubble.
