Liquid bubble

A bubble is a globule of one substance in another, usually gas in a liquid. Due to the Marangoni effect, bubbles may remain intact when they reach the surface of the immersive substance.

Common examples

Bubbles are seen in many places in everyday life, for example:

  • As spontaneous nucleation of supersaturated carbon dioxide in soft drinks
  • As water vapor in boiling water
  • As air mixed into agitated water, such as below a waterfall
  • As sea foam
  • As given off in chemical reactions, e.g., baking soda + vinegar
  • As a gas trapped in glass during its manufacture
  • An air bubble in a solution of fluorescein and water (or alcohol) is the essential part of a spirit level
  • Physics and chemistry

    Bubbles form, and coalesce, into globular shapes, because those shapes are at a lower energy state. For the physics and chemistry behind it, see nucleation.

    Appearance

    Humans can see bubbles because they have a different refractive index (IR) than the surrounding substance. For example, the IR of air is approximately 1.0003 and the IR of water is approximately 1.333. Snell's Law describes how electromagnetic waves change direction at the interface between two mediums with different IR; thus bubbles can be identified from the accompanying refraction and internal reflection even though both the immersed and immersing mediums are transparent.
