Physical vs. Chemical Properties

Characteristic that can be observed without the matter

changing identity

PHYSICAL PROPERTIES

Malleability- the ability to be hammered into thin

sheets

EXAMPLES (FROM YOUR OWN LIFE)

Ductility- the ability to be drawn into wire

Electric conductivity-the ability to carry

electricity


Density- how tightly matter is packed

The density of water= 1.0 g/cm3


Iron reacts with oxygen to form rust

NON-EXAMPLES (FROM YOUR OWN LIFE)

Gasoline burns in a car engine


The copper in the Statue of Liberty has reacted with carbon dioxide to from

copper carbonate (the green stuff on the statue)


Rubbing alcohol is flammable

NON EXAMPLES (FROM YOUR OWN LIFE)

Characteristic that can be observed only as the matter

changes identity

CHEMICAL PROPERTIES

• wood is flammable


• Copper reacts with CO2, formingcopper carbonate


• Hydrogen is flammable


• Stainless steel does not react with oxygen (rust)


• Helium is not flammable


Helium is less dense than air


Solubility- the ability of a substance to dissolve


Ductility- the ability to be drawn into wire

Electric conductivity-the ability to carry

electricity
