  1. If objects are the same size they will have the same density. Different materials have different densities. Density is made up of two other measurements – mass and volume. true The density of a substance is the same for all samples of the substance. The density of a substance like gold is always different. The density of water is 1 g/mL. true An object will float if it is more dense than the surrounding liquid. An object will float if it is less dense than the surrounding liquid.

  2. wood = 0.5 g/cm3 gold = 19.3 g/cm3 water = 1 g/mL 8 mL of water = 8 g 8 cm3 of wood = 4 g 8 cm3 of gold = 154.4 g

  3. 1. If you pack more mass into the same volume, it’s more dense. 2 cm 2 cm 2 cm 2 cm 2 cm 2 cm 2cm 2 cm 2 cm Mass = 8 g Mass = 16 g Mass = 24g Volume = 8 cm3 Volume = 8 cm3 Volume = 8 cm3 Density = 1 g/cm3 Density = 2 g/cm3 Density = 3 g/cm3

  4. If you pack the same mass into a smaller volume, it’s • more dense. 3 cm 2 cm 1 cm 1 cm 2 cm 1 cm 3 cm 2 cm 3 cm Mass = 54 g Mass = 54 g Mass = 54 g Volume = 27 cm3 Volume = 8 cm3 Volume = 1 cm3 Density = 2 g/cm3 Density = 6.75 g/cm3 Density = 54 g/cm3

  5. Just because something has more mass does not • mean that it’s more dense. Mass = 10 g Mass = 20 g Volume = 2 cm3 Volume = 5 cm3 Density = 5 g/cm3 Density = 4 g/cm3

  6. definition: the measure of how much mass is contained in a given volume of space density of a liquid g/mL density of a solid g/cm3 density Made up of two measurements: mass and volume mass volume density =

  7. Understanding Density mass volume Formula: Example: styrofoam mass = 8 g volume = 35 cm3 density = 0.2 g/cm3

  8. mass = 18 g volume = 20 cm3 density = 0.9 g/cm3 candle

  9. mass = 5 g volume = 2 cm3 density = 2.5 g/cm3 marbles

  10. mass = 78 g volume = 10 cm3 density = 7.8 g/cm3 iron

  11. mass = 3 g volume = 6 cm3 density = 0.5 g/cm3 beach ball

  12. mass = 35 g volume = 50 cm3 density = 0.7 g/cm3 pumpkin

  13. mass = 81 g volume = 30 cm3 density = 2.7 g/cm3 aluminum

  14. Density Definition: the measure of how much mass is contained in a given volume of space mass volume Formula: D = g/cm Units of Measurement: g/mL Booklet
