Density
(Noun) | Pronunciation: /ˈdɛnsɪti/
Definition & Meaning
The word “density” refers to the compactness, concentration, or mass of something within a given space.
- In Physics & Science – The mass of an object per unit volume (Density = Mass/Volume).
- In Population Studies – The number of people or objects in a given area.
- In General Use – The thickness, opacity, or compact arrangement of something.
💡 Did You Know? Water has a density of 1 gram per cubic centimeter, which is why objects less dense than water float!
Word Origin & History
- Etymology: Derived from Latin “densus”, meaning “thick” or “compact.”
- Historical Usage: The term has been used in scientific and mathematical contexts since the 17th century.
- Cultural Influence: Density is crucial in physics, engineering, urban planning, and even literature (e.g., describing “dense fog”).
📖 Example: The density of a city’s population affects its infrastructure and resources.
