Butter is an example of which type of colloid?

Options

A. Solid in liquid
B. Liquid in solid
C. Liquid in liquid
D. Gas in liquid.

Explanation

To determine the type of colloid that butter represents, we can follow these steps:

### Step-by-Step Solution:

1. **Understanding Colloids**:
- Colloids are mixtures where one substance is dispersed evenly throughout another. They can be classified based on the states of the dispersed phase and the dispersion medium.

2. **Identifying the Components of Butter**:
- Butter is primarily composed of fat (which is a liquid at certain temperatures) and water. The fat droplets are dispersed in the water phase.

3. **Classifying Butter**:
- Since butter consists of liquid fat dispersed in a solid matrix (the water and other components), it can be classified as a colloid.

4. **Identifying the Type of Colloid**:
- The types of colloids include:
- Solid in liquid
- Liquid in solid
- Liquid in liquid
- Gas in liquid
- In the case of butter, the fat (liquid) is dispersed in a solid (the remaining components of butter).

5. **Conclusion**:
- Therefore, butter is classified as a **liquid in solid** type of colloid.

### Final Answer:
Butter is an example of a **liquid in solid** colloid.
