  1. Properties of Matter Chapter 18 Section 2

  2. Physical Properties • Physical Property – any characteristic of a material that you can observe without changing the identity of a substance • Examples: color, shape, size, density, melting and boiling points

  3. Physical Properties • Appearance • Shape • Color • State of matter • Behavior • Magnetism • Viscosity • Malleability

  4. Physical Properties • Using Physical Properties to separate • Filter • Distillation • Use a magnet • Chromatography • Centrifuge

  5. Physical Changes • Physical Change – change is size, shape or state of matter • The identity of the element or compound does not change (new substance DOES NOT form) • Examples: Freeze, boil, evaporate, break, bend,

  6. Chemical Properties and Changes • Chemical Property – characteristic of a substance that indicates whether it can through a chemical change • Flammability • Combustibility • pH

  7. Chemical Changes • Chemical change – a change from one substance to another, a change in chemical identity • Rusting, burning, digesting food, baking soda and vinegar • Clues to chemical changes: • Heating, cooling, formation of bubbles or solids

  8. Weathering – chemical of physical • Physical • Large rocks split when water seeps in the cracks and then freezes • Streams cut through softer rocks and form canyons

  9. Weathering – physical or chemical • Chemical • Limestone undergoes a chemical change when slightly acidic rainfall hits it. • Formation of stalactites in caves

  10. The Conservation of Mass • The mass of all the substances that are present before a chemical change has to equal the mass of the substances after the change.
