Identify an intensive property among the following

Options

A. Gibbs free energy
B. volume
C. internal energy
D. temperature

Answer

To identify an intensive property among the given options, we need to understand the distinction between intensive and extensive properties.

### Step-by-Step Solution:

1. **Define Intensive and Extensive Properties**:
- Intensive properties are those that do not depend on the amount or size of the material in the system. They remain constant regardless of how much substance is present.
- Extensive properties, on the other hand, depend on the amount of material present. They change when the size or amount of the sample changes.

2. **Examples of Intensive Properties**:
- Common examples of intensive properties include:
- Density: The mass per unit volume of a substance.
- Temperature: A measure of the average kinetic energy of particles in a substance.
- Refractive Index: A measure of how much light bends when it enters a material.
- Hardness: A measure of a material's resistance to deformation.

3. **Examples of Extensive Properties**:
- Common examples of extensive properties include:
- Mass: The quantity of matter in a substance.
- Volume: The space occupied by a substance.
- Length: The measurement of distance.
- Energy: Total energy depends on the amount of substance.

4. **Identify the Correct Option**:
- From the definitions and examples, we can analyze the options provided. We need to select the property that remains constant regardless of the amount of material present.

5. **Conclusion**:
- After evaluating the properties, we can conclude that temperature is an intensive property because it does not change with the size or amount of the sample.

### Final Answer:
The intensive property among the options is **Temperature**.
