Density is a fundamental concept in physics and materials science, defining how much mass is contained in a given volume of a substance. Mathematically, density is expressed as mass divided by volume. This property is crucial for identifying materials, understanding buoyancy, and predicting how substances interact in different environments. Density varies among substances due to differences in molecular structure and composition. For example, metals typically have higher densities than liquids or gases. Temperature and pressure also affect density; as temperature increases or pressure decreases, most substances expand, leading to a decrease in density.
