Which is intensive property ?

Options

A. (a)Mass
B. (b)Mass/volume
C. (c)Volume
D. (d)None

Answer

To determine which of the given options is an intensive property, we need to understand the definitions of intensive and extensive properties.

### Step-by-Step Solution:

1. **Understand the Definitions**:
- **Intensive Properties**: These are properties that do not depend on the amount of substance or the size of the system. Examples include temperature, pressure, and density.
- **Extensive Properties**: These properties depend on the amount of substance or the size of the system. Examples include mass, volume, and total energy.

2. **Analyze the Options**:
- **Option A: Mass**: Mass is an extensive property because it depends on the amount of substance present. Therefore, this option is not correct.
- **Option B: Mass by Volume**: This is equivalent to density (Density = Mass/Volume). Density is an intensive property because it does not change regardless of the amount of substance present. Thus, this option is correct.
- **Option C: Volume**: Volume is also an extensive property because it depends on the size of the system. Therefore, this option is not correct.
- **Option D: None**: This option is incorrect since we have already identified an intensive property in option B.

3. **Conclusion**:
- The only intensive property among the given options is **mass by volume**, which is density.

### Final Answer:
The intensive property among the given options is **mass by volume (density)**.
