Density

Den"si*ty\, n. [L. densitas; cf. F. densit['e].]

1. The quality of being dense, close, or thick; compactness; -- opposed to rarity.

2. (Physics) The ratio of mass, or quantity of matter, to bulk or volume, esp. as compared with the mass and volume of a portion of some substance used as a standard.

Note: For gases the standard substance is hydrogen, at a temperature of 0[deg] Centigrade and a pressure of 760 millimeters. For liquids and solids the standard is water at a temperature of 4[deg] Centigrade. The density of solids and liquids is usually called specific gravity, and the same is true of gases when referred to air as a standard.

3. (Photog.) Depth of shade. --Abney.
Language Translation for : density
Spanish: densidad,
German: die Dichte,
Japanese: 密度

density

The relative heaviness of objects, measured in units of mass or weight per units of volume. (See specific gravity.)

density den·si·ty (děn'sĭ-tē)
n.

  1. The mass per unit volume of a substance at a specified pressure and temperature.
  2. The quantity of something per unit measure, especially per unit length, area, or volume.

density   (děn'sĭ-tē)  Pronunciation Key 
A measure of the quantity of some physical property (usually mass) per unit length, area, or volume (usually volume). ◇ Mass density is a measure of the mass of a substance per unit volume. Most substances (especially gases such as air) increase in density as their pressure is increases or as their temperature decreases. ◇ Energy density is a measure of the amount of energy (often in the form of electromagnetic radiation) per unit volume in a region of space or some material. See also Boyle's law.
