    Name the dispersed phase and dispersion medium in milk.

    Read the given passage and answers following questions : Emulsion: It is a colloidal mixture in which both the dispersed phase and the dispersion medium are liquids. The two or more liquids present in the mixture are generally immiscible in nature. Example: Milk. Gel: It is a colloid in which the dispersed phase i.e. liquid has combined with the dispersion medium i.e. solid to produce a semisolid material. Example: jellies. Answer the following questions : Which type of material formed when dispersed phase and dispersion medium combined ?
