What is density? 
measures how closely packed together a substance's particles are.
What does density compare?
the mass of materials with the same volume.
What is the equation for density?
Density = mass/volume
What is density given in?
kg/m3
What else can density be given in?
g/cm3
What does 1 g/cm3 equal to in kg/m3?
1000 kg/m3
Why do liquids & gases have a lower density than solids?
the particles are not as tightly packed as the particles of a solids. The particles in a gas are more spread out, unless compressed.
What does density depend on?
material & how the particles are arranged.
How are particles in a dense material?
tightly packed together.
