Q. What do you mean by Emulsions?

Emulsions, as you may already know by now, are colloidal dispersions of a liquid in another liquid with which it is immiscible. Emulsions can be formed by shaking the two liquids together until they appear to be well mixed. Shaking provides the energy needed to enable the liquid with the higher surface tension to form many small droplets or spheres which then are surrounded by the other liquid. Formation of these numerous small spheres creates a far larger surface area for the dispersed liquid that was the case when two liquids were in contact as two layers.

The droplets of the dispersed phase tend to coalesce when they bump into each other as they move through the emulsion because the one large droplet represents a lower energy state than two. Because one large droplet has less surface area than two small droplets, thus the droplets in an emulsion continue to coalesce into larger droplets until the emulsion breaks or separates into two distinct phases.
