Choose the intensive property from the options given below

Options

A. volume
B. mass
C. refractive index
D. weight

Answer

To solve the question of identifying the intensive property from the given options, we need to understand the definitions of intensive and extensive properties.

### Step-by-Step Solution:

1. **Understand the Definitions**:
- **Intensive Property**: An intensive property is a property that does not change with the amount of substance present. Examples include temperature, pressure, density, and refractive index.
- **Extensive Property**: An extensive property is a property that does change with the amount of substance. Examples include mass, volume, and weight.

2. **Analyze the Options**:
- We need to evaluate each option provided to determine whether it is intensive or extensive.
- For example, if one of the options is mass, we know that mass is an extensive property because it increases with the amount of substance.
- If another option is density, we know that density is an intensive property because it remains constant regardless of the amount of substance.

3. **Identify the Correct Option**:
- After evaluating the options, we find that the refractive index is independent of the quantity of the substance. It depends on the material's properties, such as density, but not on how much of the material you have.
- Therefore, the refractive index is an intensive property.

4. **Conclusion**:
- Based on the analysis, the correct answer to the question is the refractive index, which is option C.

### Final Answer:
The intensive property from the options given is **C) Refractive Index**.
