👉 Density is a measure of mass per unit volume, expressed in units such as grams per cubic centimeter (g/cm³) or kilograms per cubic meter (kg/m³). It is a fundamental concept in physics and engineering, describing how tightly packed particles are within a material. Mathematically, density (ρ) is calculated using the formula ρ = m/V, where m is the mass of the substance and V is its volume. This relationship allows us to understand and compare the compactness of different materials, with higher density indicating a greater mass packed into a given space. Density is crucial in various applications, from material science to oceanography and meteorology, influencing properties like buoyancy, heat capacity, and fluid dynamics.
