- A solid dispersed in a liquid
- A liquid dispersed in a gas
- A liquid dispersed in a solid
- A liquid dispersed in a liquid
Hint:
A liquid dispersed in a liquid
The correct answer is: A liquid dispersed in a liquid
- They are combinations of two or more liquids. One of them is a droplet of tiny or even ultra microscopic size that is spread throughout the other. These are typically generated from the components of liquids, either naturally or through methods such as agitation, provided that the fluids involved have no kind of mutual solubility.
- It is claimed to be stabilised by substances that form coatings on the surface of droplets or that provide them mechanical stability. Emulsions' unstable structure eventually divides into two liquid layers.
- The stable emulsions are destroyed by eliminating or deactivating the emulsifying agent, such as by adding an appropriate third party.
