Which one of following properties could not be used as a temperature sensitive property in the construction of thermometer ?

Options

A. The change in mass of a solid.
B. The change in the volume of a liquid .
C. The change in length of a metal rod.
D. The change in electrical resistance of a wire.

Answer

To determine which property could not be used as a temperature-sensitive property in the construction of a thermometer, we will analyze the options provided.

### Step-by-Step Solution:

1. **Understanding Temperature-Sensitive Properties**:
- A temperature-sensitive property is one that changes in response to temperature variations. This change can be measured and used to indicate the temperature.

2. **Analyzing Volume**:
- The volume of liquids, such as mercury, expands when heated. This property is commonly used in thermometers. Therefore, volume can be used as a temperature-sensitive property.

3. **Analyzing Length**:
- The length of a solid object (like a metal rod) changes with temperature due to thermal expansion. This linear expansion can be measured and is also a temperature-sensitive property.

4. **Analyzing Electrical Resistance**:
- The electrical resistance of materials changes with temperature. The relationship can be expressed as \( R' = R_1 + \alpha \Delta T \), where \( \alpha \) is the temperature coefficient of resistance. Thus, electrical resistance is also a temperature-sensitive property.

5. **Analyzing Mass**:
- The mass of a solid does not change with temperature. It remains constant regardless of temperature changes. Therefore, mass cannot be used as a temperature-sensitive property.

6. **Conclusion**:
- Based on the analysis, the property that could not be used as a temperature-sensitive property in the construction of a thermometer is the change in mass of a solid.

### Final Answer:
The property that could not be used as a temperature-sensitive property in the construction of a thermometer is **the change in mass of a solid**.
