1. Comparing & Classifying Physical Properties
Distinguishing Features:
On page 47 in your notebook Make 2 columns. On top of one column title it “same” and number On the second column title it “different” and number it 1-10.
On the following slide list 10 physical features/properties that are the same and 10 physical features/properties that are different.
Physical Properties
A physical property is any characteristic of a material that can be observed or measured without changing the composition of the substance in the material.

2. Distinguishing Features

4. Solubility
The ability of a substance to dissolve in another substance.
When fully dissolved the particles spread throughout

6. CONDUCTIVITY
The measure of the ease at which an electric charge or heat can pass through a material.

8. The ability of a substance, usually a metal, to be deformed or molded into a different shape.
MALLEABILITY

10. HARDNESS
The measure of how resistant solid matter is to change in shape when a force is applied.

12. MELTING POINT
Temperature at which a substance changes from a solid to a liquid during a phase change.

14. BOILING POINT
Temperature at which a substance changes from a liquid to a gas during a phase change

16. Each element and compound has a unique density associated with it.
The qualitative manner that is used to measure the relative “heaviness” of objects with a constant volume.
Density = m/v
amount of mass/unit of volume
Each element and compound has a unique density associated with it.
EX: Lead =11.34 g/cm^3 Aluminum =2.7 g/cm^3 Water = 1.0 g/cm^3
