  1. 5.2 What are Physical Properties?

  2. Physical Properties

  3. Physical properties include: • appearance, texture, color, odor, melting point, boiling point, density, solubility, polarity, and many others. • The three states of matter are: solid, liquid, and gas. • The melting point and boiling point are related to changes of the state of matter. All matter may exist in any of three physical states of matter. • Solubility: how well something is able to dissolve

  4. 5 Senses • Sight • Smell • Taste • Touch • Hearing

  5. Viscosity • Tendency of a fluid to keep from flowing • The greater the viscosity, the slower the liquid moves

  6. Conductivity • Material’s ability to allow heat or electricity to flow

  7. Malleability • Ability of a material to be shaped or hammered without breaking

  8. Hardness • Ability of a material to be scratched

  9. Melting & Boiling Points • Each substance has their own • Can be used to identify a substance

  10. Density • Density=Mass/volume • Can be used to test the purity of a substance because all matter has a unique density

  11. 5.3 Chemical Properties How Substances Change

  12. Chemical Properties • Ability to produce a change in the composition of matter • Can be observed only as the matter is changing

  13. Combustibility (Flammability) • Material’s ability to burn in the presence of oxygen

  14. Reactivity • How readily a substance combines chemically with other substances

  15. Production of a Precipitate • When two solutions are mixed together and a insoluble solid is created.

  16. What are some differences between chemical & physical properties?

  17. What properties (physical or chemical) are helpful in identifying a substance?
