Identify the intensive quantities from the following

Options

A. enthalpy
B. temperature
C. refractive index
D. both 2 and both 3

Answer

To identify intensive quantities from a given list, we first need to understand what intensive quantities are.

### Step-by-Step Solution:

1. **Define Intensive Quantities**:
Intensive quantities are properties of a substance that do not change regardless of the amount of substance present. They are independent of the quantity of matter. Examples include temperature, pressure, density, and color.

2. **List of Given Quantities**:
(Assuming we have a list of quantities to analyze, for example: temperature, mass, volume, density, and pressure.)

3. **Analyze Each Quantity**:
- **Temperature**: This is an intensive property because it remains the same regardless of how much of the substance you have.
- **Mass**: This is an extensive property because it changes with the amount of substance.
- **Volume**: This is also an extensive property as it varies with the quantity of matter.
- **Density**: This is an intensive property because it is the ratio of mass to volume and remains constant regardless of the amount of substance.
- **Pressure**: This is an intensive property as it does not depend on the amount of the substance.

4. **Identify Intensive Quantities**:
From the analysis, the intensive quantities are:
- Temperature
- Density
- Pressure

### Final Answer:
The intensive quantities from the given options are **Temperature, Density, and Pressure**.
