density

N ความหนาแน่น  kwam-na-naen

 

Webster's 1828 Dictionary

DENSITY

n. 1. Closeness of constituent parts; compactness. Density is opposed to rarity; and in philosophy, the density of a body indicates the quantity of matter contained in it, under a given bulk. If a body of equal bulk with another is of double the density, it contains double the quantity of matter.
2. Thickness; as the density of fog.

 

Webster's 1913 Dictionary

DENSITY

Den "si *ty, n. Etym: [L. densitas; cf. F. densité. ]

 

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

 

2. (Physics )

 

Defn: 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 º Centigrade and a pressure of 76 millimeters. For liquids and solids the standard is water at a temperature of 4º 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. )

 

Defn: Depth of shade. Abney.
