📚 What is Density?

Density is a measure of how much mass is contained in a given volume. It is defined as mass per unit volume. The formula is: ρ = m / V, where ρ (rho) is density, m is mass, and V is volume.

Density is an intrinsic property of matter - it doesn't change based on how much of the substance you have. For example, a small piece of gold and a large gold bar both have the same density (19.3 g/cm³). This makes density useful for identifying substances.

📊 Density Formula & Unit Conversions

Density (ρ) = Mass (m) ÷ Volume (V)
Mass (m) = Density (ρ) × Volume (V)
Volume (V) = Mass (m) ÷ Density (ρ)

• 1 g/cm³ = 1000 kg/m³ = 1 g/mL
• Water density = 1 g/cm³ at 4°C

❓ Frequently Asked Questions

Why does ice float on water?
Ice has a density of 0.92 g/cm³, while liquid water has a density of 1.0 g/cm³. Since ice is less dense, it floats.
What is specific gravity?
Specific gravity is the ratio of a substance's density to the density of water (at 4°C). It has no units.
How does temperature affect density?
Generally, density decreases as temperature increases because materials expand.
What is the densest element?
Osmium is the densest naturally occurring element at 22.59 g/cm³.
How do I measure density experimentally?
For regular solids: measure mass and calculate volume from dimensions. For irregular solids: use water displacement.
