Meaning
Density is the amount of mass per unit volume of an object.
About Density
- An object with a large amount of mass in a small volume is said to have a high density.
- An object with a small amount of mass spread over a large volume is said to have a low density.
- The units of density are kg/m3.

| Solids are the most dense state of matter because there are a large number of particles in a certain volume and gases are the least dense state of matter because there are a small number of particles in a the same volume. |
Equation
- Density = Mass/volume
\[\rho = \tfrac{m}{V}\] Where: ρ = density m = mass V = volume
