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
EXAMPLES (FROM YOUR OWN LIFE)
Density- how tightly matter is packed
The density of water= 1.0 g/cm3
EXAMPLES (FROM YOUR OWN LIFE)
Iron reacts with oxygen to form rust
NON-EXAMPLES (FROM YOUR OWN LIFE)
Gasoline burns in a car engine
NON-EXAMPLES (FROM YOUR OWN LIFE)
The copper in the Statue of Liberty has reacted with carbon dioxide to from
copper carbonate (the green stuff on the statue)
NON-EXAMPLES (FROM YOUR OWN LIFE)
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
EXAMPLES (FROM YOUR OWN LIFE)
• Copper reacts with CO2, formingcopper carbonate
EXAMPLES (FROM YOUR OWN LIFE)
• Hydrogen is flammable
EXAMPLES (FROM YOUR OWN LIFE)
• Stainless steel does not react with oxygen (rust)
EXAMPLES (FROM YOUR OWN LIFE)
• Helium is not flammable
EXAMPLES (FROM YOUR OWN LIFE)
Helium is less dense than air
NON-EXAMPLES (FROM YOUR OWN LIFE)
Solubility- the ability of a substance to dissolve
NON-EXAMPLES (FROM YOUR OWN LIFE)
Ductility- the ability to be drawn into wire
Electric conductivity-the ability to carry
electricity
