  2. PHYSICAL PROPERTIES • A physical property is a property that can be observed or measured without changing the composition of matter. • Examples: • Color • Hardness • Malleability • Viscosity • Texture • Odor • Melting Point • Etc.

  3. CHEMICAL PROPERTIES • A chemical property shows the ability for a substance to react to other substances. • Examples: • Corrosion • Oxidation

  4. Sample1 The Metal Samples Sample 2

  5. Sample 1 Evaluation • Identity of sample 1: Aluminum • Supporting evidence: • Not magnetic • Silver in color • Density: 2.7g/mL • Doesn’t oxidize quickly • Conducts electricity www.elmhurst.edu/~chm/vchembook/102aluminum.html supports this evidence

  6. Sample 2Evaluation • Identity of sample 2: Steel • Supporting Evidence • Magnetic • Dark grey color • Density= 7.8 g/cm3 • Harder (Scratch Test) • lower thermal conductivity http://www.ndted.org/EducationResources/CommunityCollege/Materials/Physical_Chemical/PhysicalProperties.htm Supports this evidence

  7. Mystery Powder Evaluation • Identity of the mystery powder: Baking soda • Supporting Evidence • Baking soda had same reactions

  8. Mystery Liquid • Identity of the mystery liquid: Rubbing Alcohol • Supporting Evidence: • Flammable • Smell • Cold • Clear • Very high viscosity

  9. Water Rubbing Alcohol Mystery Liquid

  10. Conclusion • Metal Sample 1 is Aluminum • Metal Sample 2 is Steel • The Mystery Powder is Baking Powder • The Mystery Liquid is Rubbing Alcohol
