Also known as foams, foam material

thumb|Top of a foamy drink Foam is a 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. Foam "may contain more or less liquid [or solid] according to circumstances", although in the case of gas-liquid foams, the gas occupies most of the volume.

AI overview

Foam is a material made up of gas bubbles trapped inside a liquid or solid, where the gas typically makes up most of the volume. This mixture of gas and liquid or solid material is useful in many everyday products, from beverages to industrial applications, because it can have unique properties like lightness and texture.

thumb|Top of a foamy drink Foam is a 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. Foam "may contain more or less liquid [or solid] according to circumstances", although in the case of gas-liquid foams, the gas occupies most of the volume.

In most foams, the volume of gas is large, with thin films of liquid or solid separating the regions of gas.
