: Think of it as how "tightly packed" the matter is. For example, a cubic centimeter of bricks is much denser (1.6 g/cm³) than a cubic centimeter of feathers (0.0025 g/cm³). Key Characteristics
: An object will float in a fluid if its density is lower than the fluid's and sink if it is higher. Water has a defined density of 1.0 g/cm³.
: A material's density is determined by the mass of its individual atoms and how closely those atoms are arranged. Common Examples Density (Approx.) Air 1.29 kg/m³ Ice 917 kg/m³ Water 1,000 kg/m³ Lead 11,340 kg/m³ 💡 Pro Tip: The Density Triangle To easily rearrange the formula for different calculations: To find Mass : Density To find Volume : Mass ÷divided by To find Density : Mass ÷divided by Expert Perspectives
Users often find the relationship between size and weight the most intuitive way to grasp the concept.
