Presentation Transcript

  1. Chapter 1 Notes Section 2+3

  2. Physical Properties (characteristics) can be observed or measured without changing the object

  3. Examples: • 1. Color • 2. Odor • Thermal conductivity– ability • to transfer heat

  4. 4. Solubility ability to dissolve 5.Malleability – ability to be pounded into thin sheets 6. Ductility– ability to be pulled into thin wires

  5. Density mass per unit volume • Density is the same for the same substance • Density of one substance is usually different than the density of other substances

  6. Formula to calculate density: D = M Density = Mass (g) V Volume (mL) The density of pure water is 1 g/mL

  7. A substance with a density greater than water sinks in water A substance with a density less than water floats in water

  8. Chemical Properties are based on the ability of a substance to change into another substance with new and different properties

  9. Examples: Flammability – ability to burn Nonflammable – will not burn

  10. Reactivity with oxygen Reactivity with water Reactivity with acid

  11. Physical changes affect only the appearance of a substance

  12. Examples Melting Dissolving Sanding Cutting

  13. Bending Mixing

  14. Chemical change is a process where a substance changes into another substance

  15. Examples Color change Fizzing Sound or Light

  16. Odor Temperature
