Identify the intensive quantities from the following :
(a)Enthalpy
(b)Temperature
(c)Pressure
(d)Mass

Options

A. Enthalpy
B. Temperature
C. Pressure
D. Mass

Explanation

To identify the intensive quantities from the given options, we need to understand the distinction between intensive and extensive properties.

### Step-by-Step Solution:

1. **Understand Intensive and Extensive Properties**:
- Intensive properties are those that do not depend on the amount of substance present in the system. Examples include temperature, pressure, and density.
- Extensive properties, on the other hand, depend on the amount of substance. Examples include mass, volume, and enthalpy.

2. **Analyze Each Option**:
- **(a) Enthalpy**: This is an extensive property because it depends on the amount of substance in the system. If you have more substance, the enthalpy will increase.
- **(b) Temperature**: This is an intensive property because it does not change with the size of the system. Whether you have a small or large sample, the temperature can remain the same.
- **(c) Pressure**: This is also an intensive property. Pressure is defined as force per unit area and does not depend on the size of the system.
- **(d) Mass**: This is an extensive property because it directly depends on the amount of substance present. More substance means more mass.

3. **Conclusion**:
- From the analysis, the intensive quantities among the options provided are:
- **(b) Temperature**
- **(c) Pressure**

### Final Answer:
The intensive quantities from the given options are:
- **Temperature (b)**
- **Pressure (c)**
