An emulsion consists of
An emulsion consists of
One liquid and one gas
One liquid and one solid
Two liquids
Two solids
The Correct Option is C
Solution and Explanation
An emulsion is a type of mixture that consists of two immiscible liquids, where one liquid is dispersed in the other in the form of small droplets. Typically, emulsions are classified based on the dispersion of the liquid droplets. The two basic types of emulsions are:
- Oil-in-water (O/W) emulsion: Oil droplets are dispersed in a continuous water phase.
- Water-in-oil (W/O) emulsion: Water droplets are dispersed in a continuous oil phase.
Emulsions are stabilized by substances known as emulsifiers, which reduce the surface tension between the liquids, allowing them to remain mixed without separating. Common examples of emulsions include milk (O/W emulsion) and butter (W/O emulsion).
The correct answer to the question "An emulsion consists of" is: Two liquids

Solutions
A solution is a homogeneous mixture of two or more components in which the particle size is smaller than 1 nm.
For example, salt and sugar is a good illustration of a solution. A solution can be categorized into several components.
Types of Solutions:
The solutions can be classified into three types:
- Solid Solutions - In these solutions, the solvent is in a Solid-state.
- Liquid Solutions- In these solutions, the solvent is in a Liquid state.
- Gaseous Solutions - In these solutions, the solvent is in a Gaseous state.
On the basis of the amount of solute dissolved in a solvent, solutions are divided into the following types:
- Unsaturated Solution- A solution in which more solute can be dissolved without raising the temperature of the solution is known as an unsaturated solution.
- Saturated Solution- A solution in which no solute can be dissolved after reaching a certain amount of temperature is known as an unsaturated saturated solution.
- Supersaturated Solution- A solution that contains more solute than the maximum amount at a certain temperature is known as a supersaturated solution.
