Density of materials Density of materials


The density of a material is defined by the equation:

density = massvolume

ρ = Vm

density, ρ, in kilograms per metre cubed, kg/m3mass, m, in kilograms, kg

volume, V, in metres cubed, m3

The particle model can be used to explain

  • the different states of matter
  • differences in density.
  • Students should be able to recognise/draw simple diagrams to model the difference between solids, liquids and gases.
  • Students should be able to explain the differences in density between the different states of matter in terms of the arrangement of atoms or molecules.

WS 1.2 Use a variety of models such as representational, spatial, descriptive, computational and mathematical to solve problems, make predictions and to develop scientific explanations and understanding of familiar and unfamiliar facts.
