Type of colloid wherein gas acts as the dispersed phase and solid acts as the dispersion medium. In simple words, it is a colloid where gas is dispersed in solid. Example of solid foams is marshmallow.
A colloid is a mixture of tiny particles of pure substances that disperse into a substance and do not settle over time. This means that a marshmallow's tiny particles of pure substance do not settle, they stay in their solid form (A fluffy delicious cylendar of mushy yum.)
