air bubbles

Air bubbles are small pockets of air trapped within a liquid, forming round or oval shapes. They occur naturally when a liquid is agitated or when gases dissolve and escape from the liquid. For example, boiling water releases bubbles of steam, and soap creates bubbles by trapping air within a thin film. In practical terms, bubbles can be found in beverages, underwater, or in foams. They are usually temporary, rising to the surface and popping as the air escapes. Bubbles are important in various natural processes and industries, such as aeration in water treatment or the formation of foam in firefighting agents.
