==Key Stage 5==
===Meaning===
[[Density]] of a substance is its [[mass]] per [[unit]] volume.
===About Density===
*The [[unit]]s of [[density]] are typically [[kilogram]]s per cubic metre (kg/m³) or grams per cubic centimeter (g/cm³).
*[[Density]] is a fundamental property of [[material]]s and affects buoyancy, stability, and structural integrity.
*The [[density]] of a substance can change with [[temperature]] and [[pressure]].
*'''Density''' is used in calculating the [[mass]] of an [[object]] given its [[Volume (Space)|volume]], and vice versa.
===Formula===
Given by the formula
𝜌 = 𝑚𝑉
, where
𝜌
ρ is the density,
𝑚
m is the mass, and
𝑉
V is the volume.
===Examples===
The density of water is approximately 1000 kg/m³.
The density of gold is much higher than that of [[aluminium]], making gold heavier for the same volume.
