Density in Science

Density is a fundamental property of matter. It determines whether substances mix, how fluids behave, and why some materials are better for specific applications.

Common Densities (kg/m³)

  • Air (at sea level): ~1.2
  • Water (4°C): 1,000
  • Aluminum: 2,700
  • Iron: 7,870
  • Gold: 19,300
  • Neutron star: ~10¹⁷

Frequently Asked Questions

Density is a measure of mass per unit volume. It describes how much matter is packed into a given space. The SI unit is kg/m³.
