What is foam?

Jesús Gracia Fadrique

Foam structure and behavior can be illustrated by means of basic Surface Physics concepts like surface tension, the adsorption or the surface-active solute concentration, the pressure difference on spherical surfaces pointed out by Young and Laplace, and the elasticity of a liquid film associated with the changes of surface tension due to the area.

Keywords: Foam, surface tension, elasticity, adsorption, curvature.
