Foams

Foams, in the context of chemistry and everyday language, refers to a substance formed by trapping pockets of gas within a liquid or solid. These pockets are usually stabilized by a surface tension effect, creating a bubbly, often lightweight structure. The size and shape of the gas bubbles, the type of liquid or solid matrix, and the presence of additives all influence a foam's properties, such as stability, density, and texture. foams can range from rigid to flexible, and they have diverse applications, from insulation and cushioning to cleaning and firefighting.
