The map in words

  • Density and Measurement
    • Density
      • Definition
        • Mass per unit volume
        • d = M divided by V
      • Units
        • SI: kg per m cube
        • CGS: g per cm cube
        • Conversion: 1 g cm-3 = 1000 kg m-3
      • Properties
        • Independent of shape or size
        • Decreases with temperature rise
        • Max density of water at 4 degree C
    • Measurement Methods
      • Regular Solids
        • Use geometric formulas
        • Measure dimensions with ruler
      • Irregular Solids
        • Measuring Cylinder
        • Eureka Can
        • Principle: Displacement
      • Liquids
        • Measuring Cylinder and Beaker
        • Density Bottle
    • Relative Density
      • RD = Density of substance divided by Density of water
      • No unit
      • RD equals density value in g per cm cube
      • Density bottle measurement
    • Floatation and Sinking
      • Buoyant Force
        • Equal to weight of liquid displaced
        • Acts upward
      • Sinks if density of body greater than liquid
      • Floats if density of body less than liquid
      • Law of Floatation
        • Weight of body equals weight displaced
    • States of Matter
      • Solid: Maximum density
      • Liquid: Medium density
      • Gas: Minimum density
      • Exception: Ice less dense than water
