Is foam a liquid or a solid?

A foam is a substance made by trapping air or gas bubbles inside a solid or liquid. Typically, the volume of gas is much larger than that of the liquid or solid, with thin films separating gas pockets. Another definition of foam is a bubbly liquid, particularly if the bubbles, or froth, are undesirable.

What is foam in chemistry?
