The measure of how closely packed particles of matter are in a certain amount of space is called density. Density is defined as the mass of a substance divided by its volume, representing how much matter is packed into a given space.
Explanation of Density
- Density describes how tightly particles are arranged in solids, liquids, or gases.
- The more closely packed the particles, the higher the density of the material.
- It is often expressed mathematically as Density=massvolume\text{Density}=\frac{\text{mass}}{\text{volume}}Density=volumemass, typically in units like grams per cubic centimeter (g/cm³) or kilograms per cubic meter (kg/m³).
This concept helps differentiate materials and explains why some objects with the same volume can have different weights due to differences in particle packing.
