All foams are liquid during formation. Some remain liquid while others cure or cool to solids.
Polyurethane foam can be cleaned with a mixture of vinegar and water. Pour the solution on a soft cloth and rub the foam, rinse, and let dry.
Foam is a solution of soap in water.
Antifoam works by disrupting the foam-forming process. It reduces surface tension, destabilizes foam bubbles, and helps them to collapse. Antifoam agents can also spread across the liquid surface to prevent foam formation by breaking up the foam bubbles.
Yes glue is a mixture, and it is also a solution.
Shaving foam is an example of foam. It is a lightweight, frothy substance that is used to help lubricate the skin during shaving. Shaving foam is made up of tiny air bubbles dispersed in a liquid solution.

In a Compressed Air Foam System (CAFS), air or another gas is compressed and introduced into the foam solution. Larger systems use a dedicated air compressor and compresses regular air from the atmosphere. Smaller systems can use any inert compressed gas such as Carbon Dioxide (CO2), Compressed Nitrogen (N2) or smaller tanks of compressed regular air. The simplest, most efficient and least expensive way of producing foam is with a portable foam eductor. These foam systems use regular hand lines and an eductuor 100 feet from the end of the nozzle. The eductor siphons foam solution from a tank or drum using the "Venturi" principal. When the foam solution reaches a standard fog nozzle, water pressure and the broken stream produced by the nozzle introduce air into the foam solution. There are other forms of nozzles that introduce water using the "Venturi" effect that are not user adjustable like a fog nozzle. The quick easy answer is regular air is used most commonly in fire fighting foam however CO2 and N2 can be used depending on the design of the system used.

Sulfuric acid solution does not foam when mixed. It is a clear, colorless liquid that is highly corrosive and can cause severe burns upon contact with the skin. Mixing it with water should be done carefully to avoid splashing and to dilute its strength.
The liquid is a solution of soap in water.
Probably due to evaporation of the water, causing dissolved substances to come out of solution.
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.
