Shaving foam is a Liquid, it has a definite volume, but no definite shape. Solids have definite shape and gases have indefinite volume
Yes glue is a mixture, and it is also a solution.
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.
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.
The white foam is a mixture of a liquid and gasses.
* solid particles dispersed in a gas (solid aerosol); example: dust in air * liquid droplets dispersed in a gas (liquid aerosol); example: cloud * solid particles dispersed in a liquid (sol); examples: slime, paste * gas dispersed in a liquid (foam); example: whipped cream * liquid in a liquid (emulsion); example: hand lotion * gas dispersed in a solid (solid foam); example: foam rubber * liquid dispersed in a solid (gel); example: jelly * solid in solid (solid sol); example: some glasses
liquid not solid or gas
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.
It is a solid depending on how you use it, if so you melt it in a warm temperature, it would become runny and runny like a liquid but it is never a gas and there is no ways to make it a gas. Scientists and dermeoligists have proved this with companionally help from the specialists and have said that shampoo, hair gels, hair lotions and shaving cream are known to be solids. With shaving cream, the cream is a liquid with many many air holes but if you leave it overnight, it becomes a solid. Hope this helped!
Gas dispersed in a liquid makes a foam. For example a shaving foam or cream or in medicine.
Shaving cream is a liquid soap with a lot of gas bubbles mixed in it. It's the gas that makes it so frothy and thick that it is able to keep its shape. When the shaving cream stands overnight, the liquid in it evaporates, and all that is left where the gas bubbles once were, is a very light and thin solid layer of soap. So you can see that shaving cream has the characteristics of all three states.
colloid: Classification of Colloids A gas may be dispersed in a liquid to form a foam (e.g., shaving lather or beaten egg white) or in a solid to form a solid foam (e.g., styrofoam or marshmallow). ... In still other cases (e.g., a dispersion of a protein in water) the particles are actually very large single molecules.
