Pronunciation: [dˈɛnsɪti] (IPA) 
Density (/ˈdɛnsɪti/) is a measure of how much mass is contained in a given volume. The word is spelled with a "d" at the start and "ity" at the end. The vowel sound in the first syllable is pronounced as "eh" as in "men" and "bed". The second syllable has the "s" sound, followed by the "i" sound as in "bit", and the "t" sound at the end. Overall, the IPA transcription of the word density is, dɛnsɪti.
Density is a physical quantity that describes the compactness or concentration of matter in a substance or object. It is defined as the mass of an object divided by its volume, indicating the amount of mass per unit volume. In other words, density is a measure of how much "stuff" is packed into a given space.
The standard unit of density in the International System of Units (SI) is kilograms per cubic meter (kg/m³). However, other popular units include grams per cubic centimeter (g/cm³) and pounds per cubic inch (lb/in³), depending on the context.
The concept of density helps in understanding and comparing the properties of different materials. For example, substances with high density such as metals like lead or gold are often described as "heavy" because they have a larger amount of mass packed into a small volume. On the other hand, materials with low density like air or helium are referred to as "light" because they have less mass per unit volume.
Density is widely used in various scientific fields, including physics, chemistry, and engineering. It allows scientists to determine the suitability of materials for specific applications and plays a crucial role in studying objects' buoyancy, as denser materials tend to sink while less dense materials float. Additionally, density is utilized in calculating the concentration of solutions, investigating the behavior of fluids, and analyzing the composition of materials through techniques like density measurements and density gradients.
1. The compactness of a substance, the amount of it in a given unit of space. 2. The quantity of electricity on a given surface or in a given time per unit of volume.

The word "density" originated from the Latin term "densitas", which is derived from the adjective "densus" meaning "thick" or "dense" in Latin. The word was then adapted into Middle English as "densite", which eventually evolved into its current form, "density", in Modern English.
