Density is a measure of how much mass is packed into a given volume. It's calculated by dividing the mass of an object by its volume (Density = Mass/Volume). A higher density means more mass is crammed into a smaller space.
Examples of Density of Matter
Here are some examples illustrating the density of different materials, measured in kilograms per cubic meter (kg/m³):
-
Gases:
- Air: 1.23 kg/m³ (relatively low density)
- Carbon Dioxide: 2 kg/m³ (slightly denser than air)
-
Liquids:
- Water: 997 kg/m³ (a common reference point)
-
Solids:
- Wax: 960 kg/m³ (less dense than water)
- Glass: 2,500 kg/m³ (significantly denser than water)
- Diamond: 3,500 kg/m³ (very dense)
- Brass: 8,530 kg/m³ (much denser than water)
- Stainless Steel: 7,800 kg/m³ (dense metal)
These examples demonstrate a wide range of densities across different states of matter. The density of a substance is affected by factors such as its composition, temperature, and pressure. For example, cold water is denser than warm water.
