Presentation Transcript

  1. Matter anything that has mass and takes up space.

  2. States of Matter Solid Liquid Gas Plasma

  3. Mixture – physical blend of 2 or more pure substances -can be separated by physical means -Homogeneous or Heterogeneous

  4. Compounds –chemical combination of 2 or more different elements -can be broken down chemically - has properties different from its component elements

  5. Two types of Physical Properties Extensive properties- dependent upon the amount of substance present e.g. mass, length, volume Intensive properties- independent of the amount of substance present. e.g. density

  6. Chemical Properties -ability of a substance to combine with or change into one or more other substances e.g. Iron -forms rust when combined with Oxygen -when combined with Nitrogen at RT, no change occurs

  7. Physical changes changes that do not result in the production of a new substance melting crushing freezing cutting breaking painting condensing bending

  8. Chemical changes chemical reactions -changes that result in the production of another substance digestion respiration burning photosynthesis decomposition

  9. Chemical Reaction substances change into new substances Exothermic reaction- releases heat Endothermic reaction- absorbs heat

  10. Some ways to determine if a chemical reaction has taken place: 1. disappearance of reactants 2. appearance of products 3. color change 4. gas/bubble production 5. precipitate formation 6. heat production- exothermic 7. heat absorption- endothermic
