Fog is an example statement is false

Options

A. Liquid is dispersed in gas
B. Gas dispersed in gas
C. Solid dispersed in gas
D. Gas dispersed in liquid

Explanation

To determine whether the statement "Fog is an example of a colloidal system" is false, we need to analyze the nature of fog and its components.

### Step-by-Step Solution:

1. **Understanding Fog**:
- Fog is a collection of tiny water droplets suspended in the air.
- It occurs when water vapor condenses into small droplets, which remain dispersed in the atmosphere.

2. **Identifying the Phases**:
- In fog, the dispersed phase is the liquid (water droplets).
- The dispersion medium is the gas (air).

3. **Classifying Fog**:
- Since fog consists of liquid droplets dispersed in a gas, it fits the definition of a colloidal system.
- Colloids are mixtures where one substance is dispersed evenly throughout another.

4. **Conclusion**:
- Therefore, the statement "Fog is an example of a colloidal system" is true, not false.

### Final Answer:
The statement "Fog is an example of a colloidal system" is **true**.
