Frequently Asked Questions

Density (ρ) is a material property defined as mass per unit volume: ρ = m/V. It is measured in g/cm³ (or g/mL) for liquids and solids, and kg/m³ for gases. Water has a density of 1.00 g/cm³ at 4°C, which makes it a convenient reference. Denser materials have more mass packed into the same volume.

Ice has a density of about 0.917 g/cm³, which is less than liquid water (1.00 g/cm³). When water freezes, its molecules form a hexagonal crystal lattice that actually takes up more space than liquid water. This unusual property — water being denser as a liquid than as a solid — is critical for aquatic life, as it allows ice to insulate liquid water below.

Density varies enormously: Air ~0.0013 g/cm³, Wood 0.4–0.9 g/cm³, Water 1.0 g/cm³, Aluminum 2.7 g/cm³, Iron 7.87 g/cm³, Gold 19.3 g/cm³. This is why a block of gold feels unexpectedly heavy — it is about 7× denser than aluminum of the same size. Osmium (22.59 g/cm³) is the densest natural element.
