Density \Den"sity\, n. [L. densitas; cf. F. densit[82].] 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.
