Properties of Matter

Physical Property• Characteristic of a substance that can be observed

and measured without changing the identity of the substance.

Examples of Physical Properties

• Density• Electrical Conductivity • Thermal Conductivity• Malleability• Luster• Melting Point• Magnetic Attraction• Boiling Point

Chemical Property

• Describes a substances ability to change into a new substance with different properties

Examples of Chemical Properties

• Flammability• Reactivity

(Rust)

Physical Properties

Density Review

• Amount of mass in a given volume• D = m/V• Units – g/cm3

– g/mL
