Physical Properties • Characteristic that can be observed without the matter changing identity
Examples (from your own life) • 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
Non-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
Chemical Properties • Characteristic that can be observed only as the matter changes identity
Examples (from your own life) • 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
Non-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
