Physical Properties of Matter (Chapter 2)

• All 7 physical properties:

  1. Electrical conductivity
  2. Thermal conductivity
  3. Melting point
  4. Boiling point
  5. Strength
  6. Hardness
  7. Flexibility
• Electrical conductivity


  Ability of electric current to flow through a material easily
• Thermal conductivity 


  Ability of a material to transfer heat
• Melting point


  Temperature when a substance changes from a solid to liquid state
• Boiling point


  Temperature when a substance changes from liquid to gaseous state
• Hardness


  Resistance of a material to wear and tear and scratches
• Strength


  Ability of a material to support a heavy load without changing its shape permanently
• Flexibility


  Ability of a material to bend without breaking
• Volume


  -Amount of space an object occupies

  -S.1. Unit: M^3

  -Regular object volumes can be determined by using a mathematic formula

  -Irregular object volumes can be determined by using displacement can
• Density


  -Measures Mass/Volume of a substance

  -S.1. Unit: Kg/m^3

  -An object with a lower density floats in the object with higher density

  -An object with a higher density sinks in the object with lower density
