Study Notes
Density
- Density is the mass of a substance per unit volume
- Represented by the symbol 'ρ' (rho)
- Formula: Density = Mass/Volume
- Units: kg/m³
- If the volume of an object is 'V', and the mass is 'm', then density (ρ) = m/V
- Density is always positive
- Density describes how tightly packed the particles of a substance are
