Let's carefully review and categorize the properties of lead listed in Alisha's table:
1. Density: 11.34 g/cm³
- This property is quantitative because it is a numerical measurement and can be measured with specific units (grams per cubic centimeter).
2. Soft
- This property is qualitative because it describes the characteristic of lead without using numerical measurements. It is based on sensory perception.
3. Solid at room temperature
- This property is qualitative because it describes the state of lead based on its physical properties at room temperature. It does not involve a numerical value but rather a descriptive observation.
4. Dull gray at room temperature
- This property is qualitative because it describes the appearance of lead without using numerical measurements. It is based on visual observation.
5. Boiling point: 174.9°C
- This property is quantitative because it is a numerical measurement and can be measured precisely with units (degrees Celsius).
6. Melting point: 327.5°C
- This property is quantitative because it is a numerical measurement and can be measured precisely with units (degrees Celsius).
7. Malleable
- This property is qualitative because it describes the characteristic of lead based on its ability to be shaped or deformed without breaking. It does not involve a numerical value.
8. Corrosion-resistant
- This property is qualitative because it describes lead's resistance to corrosion without using numerical measurements. It is based on the material's behavior over time.
Given these categorizations, the incorrectly placed item is:
- Solid at room temperature, which should be under the Qualitative column but is currently in the Quantitative column.
Therefore, Alisha incorrectly placed "Solid at room temperature," which should be in the Qualitative column.
