Foam - Wikipedia
Foams are two-phase material systems where a gas is dispersed in a second, non-gaseous material, specifically, in which gas cells are enclosed by a distinct liquid or solid material. [ 1 ] : 6 [ 2 ] : 4 [ 3 ] The foam "may contain more or less liquid [or solid] according to circumstances", [ 1 ] : 6 although in the case of gas-liquid foams, the ...
Foam | Structure, Properties, Uses | Britannica
foam, in physical chemistry, a colloidal system (i.e., a dispersion of particles in a continuous medium) in which the particles are gas bubbles and the medium is a liquid. The term also is applied to material in a lightweight cellular spongy or rigid form.
