Presentation Transcript

  1. Physical Properties

  2. Physical Properties • Characteristic of a substance that does not involve a chemical change. • density • Color • Hardness • Smell • Magnetism • Conductivity • Flexibility • State • Ductility • Malleability • Solubility

  3. Density • Ratio of the mass of a substance to the volume of the substance • Amount of matter in a given space or volume

  4. Density of Solids • Can determine if an object will float • If an object is less dense than the water, the object will float. • If an object is more dense than water, the object will sink.

  5. Solving for Density • D = M/V • g/cm³ (Solid) • kg/m³ (Solid) • kg/L (Liquid) • g/ml (Liquid) • Always the same at a given temperature and pressure Using Density to Identify Substances

  6. Physical Changes • Physical Change: • A change that affects one or more physical properties of a substance. • Does not change the identities of the substance. • Water to Ice • Dissolved salt Examples:

  7. Matter and Physical Changes • Do not change the identity of the matter involved. • Melted butter
