  1. PROPERTIES OF MATTER PHYSICAL AND CHEMICAL

  2. PHYSICAL PROPERTIES: • can be used: • -to identify a material, • -to choose a material for a specific • purpose, • to separate the substances • in a mixture

  3. EXAMPLES OF PHYSICAL PROPERTIES

  4. VISCOSITY The tendency of a liquid to keep from flowing: RANK IN ORDER of Increasing viscosity.

  5. CONDUCTIVITY A materials ability to allow heat to flow through it. Rank in order of increasing Conductivity.

  6. MALLEABILITY The ability of a solid to be hammered without shattering. Rank in order of increasing malleability.

  7. Melting or Boiling Point The temperature at which the state Of matter changes (solid to liquid, Liquid to gas.) Which has a higher melting point?

  8. DENSITY ratio between mass and volume. Can be used to test purity, since all substances have specific, unchanging densities. It is a measure of how much mass is in a certain volume.

  9. CHEMICAL PROPERTIES Any ability to produce a Change in the composition Of matter. Can be observed when substances are changing into different substances.

  10. EXAMPLES: FLAMMABILITY-ability to Burn in the presence of oxygen. REACTIVITY-how readily a substance combines chemically with other substances.

  11. HOW TO RECOGNIZE A CHEMICAL CHANGE A NEW substance will ALWAYS be formed. Change in color – Production of a gas Formation of a precipitate Change in energy (heat or light)
