Foams are gas bubbles surrounded by a liquid layer.
They can be made up of soaps, shampoos, soaps and other organic materials. Foam molecules are hydrophobic and therefore have no affinity for water.
When they come in contact with her, they tend to walk away. Foam floats above water because at this location surface tension creates holes that allow water molecules to be present, but at some points it becomes weaker at the top of the liquid.
The foam of the waves is formed of organic materials that exist in the sea water.
Foam can also be found in the solid state, such as styrene, which is better known as styrofoam.
