Density is a fundamental physical property of matter that measures how much mass is contained within a specific volume. This metric is crucial across various scientific and industrial disciplines, from material engineering and fluid dynamics to determining whether an object will float or sink in water.
Density Equation
Density (ρ) = Mass (m) / Volume (v)
Standard units are typically kilograms per cubic meter (kg/m³) or grams per cubic centimeter (g/cm³).

Frequently Asked Questions (FAQ)
Why do some heavy objects float?
Buoyancy depends on density, not just mass. A massive steel ship floats because its hull encloses a large volume of air, making its overall average density lower than the density of the water it displaces.
Does temperature affect density?
Yes. For most substances, heating causes molecules to spread apart, increasing volume and thereby decreasing density. Water is a notable exception; it expands when it freezes into solid ice, making ice less dense than liquid water.
