There is more than one kind of foam. Styrofoam is a solid mixed with gas. Soap suds are made of a liquid mixed with gas. I would call foam, in technical terms, a composite material. It's made of more than one thing.
No, foam consists of bubbles of gas trapped in a liquid or solid.
A very fine foam may be considered a colloid.
yes, foam is a heterogeneous mixture, that is made up of a gas-liquid emulsion.
By definition foam (bubbles) made of the liquid on which it is floating + a lighter gas, will always float on that liquid.
Color, density, chemical composition, stability, corrosivity, refractive index are very different.
Foam is a substance that consists of two states of matter: a gas and a liquid or solid. The liquid or solid traps the gas inside.
Liquid foam is a colloid
solid
Yes glue is a mixture, and it is also a solution.
solution
because the gas dispersed in a solid
A solution is not always a liquid: An alloy like brass is a solid in solid solution, and air is a gas in gas solution.
Foam at the top of a glass of beer is liquid combined with gas. Liquid foam with gas is also called froth. A foam sponge would be an example of a solid with air ( a gas ) pockets throughout. Similarly, volcanic rock which is lightweight, has plenty of gas bubbles throughout. Also there are more technologically advanced solid foams used in industry which are made of metals like aluminum, steel or even non metals like solid carbon. Therefore, foam can either a solid or a liquid.

a solid.
A solid foam contains water and gas dissolved with each other

The white foam is a mixture of a liquid and gasses.
A solution is not always a liquid: An alloy like brass is a solid in solid solution, and air is a gas in gas solution.
It is possible for a gas to dissolve into a solid, in which case you could say that the mixture of solid and gas is a type of solution. An example is hydrogen dissolving in platinum.
There do not appear to be any solid in gas solutions.However, hydrogen dissolved in palladium is a gas in solid solution.
A solution can be a solid, liquid, & gas.
