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.

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.
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
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
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
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
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 =
Understanding Density mass volume Formula: Example: styrofoam mass = 8 g volume = 35 cm3 density = 0.2 g/cm3
mass = 18 g volume = 20 cm3 density = 0.9 g/cm3 candle
mass = 5 g volume = 2 cm3 density = 2.5 g/cm3 marbles
mass = 78 g volume = 10 cm3 density = 7.8 g/cm3 iron
mass = 3 g volume = 6 cm3 density = 0.5 g/cm3 beach ball
mass = 35 g volume = 50 cm3 density = 0.7 g/cm3 pumpkin
mass = 81 g volume = 30 cm3 density = 2.7 g/cm3 aluminum
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
