Question

Milk is an example of a foam.

• A. True
• B. False

Answer 1

The correct option is B False

A colloidal solution is a heterogeneous mixture in which particles having a size bigger than a true solution but smaller than that of a suspension are dispersed in a continuous dispersion medium.

• The dispersion medium is the continuous medium in a colloid, and the particles are the dispersed phase.
• An emulsion is a colloid consisting of two or more non-homogeneous liquid types, one of which contains a dispersion of the other.
• Milk is a milk fat (liquid phase) emulsion of water.
• Foam is a colloid that consists of a gas distributed in a liquid media. Soap bubbles and shaving cream are two examples.

Thus, Milk is an example of foam is a false statement.
