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 1-10. 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.

Distinguishing Features

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

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

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

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

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

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

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
