  1. Physical vs. Chemical Properties

  2. Physical Properties • Characteristic that can be observed without the matter changing identity

  3. Examples (from your own life) • Malleability- the ability to be hammered into thin sheets

  4. Examples (from your own life) • Ductility- the ability to be drawn into wire • Electric conductivity- the ability to carry electricity

  5. Examples (from your own life) • Density- how tightly matter is packed • The density of water= 1.0 g/cm3

  6. Non-Examples (from your own life) • Iron reacts with oxygen to form rust

  7. Non-Examples (from your own life) • Gasoline burns in a car engine

  8. 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)

  9. Non Examples (from your own life) • Rubbing alcohol is flammable

  10. Chemical Properties • Characteristic that can be observed only as the matter changes identity

  11. Examples (from your own life) • wood is flammable

  12. Examples (from your own life) • Copper reacts with CO2, formingcopper carbonate

  13. Examples (from your own life) • Hydrogen is flammable

  14. Examples (from your own life) • Stainless steel does not react with oxygen (rust)

  15. Examples (from your own life) • Helium is not flammable

  16. Non-Examples (from your own life) • Helium is less dense than air

  17. Non-Examples (from your own life) • Solubility- the ability of a substance to dissolve

  18. Non- Examples (from your own life) • Ductility- the ability to be drawn into wire • Electric conductivity- the ability to carry electricity
