Density


Definition:

  • (n.) The quality of being dense, close, or thick; compactness; -- opposed to rarity.
  • (n.) 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.
  • (n.) Depth of shade.
