What does density relate to
The mass of a substance to how much space it takes up
What are the units for density

How do you work out the density of a substance
Density = mass/volume
What does the density of a object depend on
What it is made of
How the particles are arranged
What happens when you compress a material
The particles become more close together and the material becomes more dense
( you are not changing its mass, just decreasing the volume )
