Density Facts

  • • Density = Mass ÷ Volume (ρ = m/V)
  • • Water has a density of 1.0 g/ml at room temperature
  • • Objects less dense than water will float
  • • Temperature and pressure affect density
  • • Specific gravity is density relative to water

How it works

Density tells you how much mass is packed into a given volume. Divide mass by volume to get it. Rearranged, the same relationship finds mass from density and volume, or volume from mass and density.

Density

ρ = m ÷ V        (so m = ρ · V  and  V = m ÷ ρ)
ρ
density (e.g. g/cm³ or kg/m³)
m
mass
V
volume

Worked example

  • Mass = 200 g
  • Volume = 100 cm³
  1. ρ = 200 ÷ 100

Density = 2 g/cm³.

Good to know

  • Water is ~1 g/cm³, so anything denser than 1 sinks and anything less floats.
  • Keep units consistent — g with cm³, or kg with m³ — or convert first.
  • Density changes with temperature (things expand when heated), so values are usually quoted at a reference temperature.

Häufig gestellte Fragen

How do you calculate density?

Density = Mass ÷ Volume. Common units are g/cm³ for solids/liquids and g/L for gases. Water has a density of 1 g/cm³ at room temperature.

Why is density important?

Density helps identify materials, predict buoyancy, calculate material quantities for construction, and solve engineering problems involving weight and volume.

How does temperature affect density?

Most materials become less dense when heated (thermal expansion) and denser when cooled. Water is unusual - it's densest at 4°C, not at freezing.
