Final answer:
True. Emulsions and foams are both colloidal systems in which one immiscible phase is dispersed in another.
Step-by-step explanation:
True. Emulsions and foams are both colloidal systems in which one immiscible phase is dispersed in another.
An emulsion is a colloidal dispersion of a liquid in either a liquid or solid. It is formed by shaking or blending two immiscible liquids, breaking one liquid into droplets that disperse throughout the other liquid.
A foam is a colloidal dispersion of gas bubbles in a liquid or solid. It can be formed by whipping or mixing a gas with a liquid or solid, creating a dispersion of gas bubbles throughout the substance.
