density
n 1: the amount per unit size [synonym: {density}, {denseness}]
2: the spatial property of being crowded together [synonym:
{concentration}, {density}, {denseness}, {tightness},
{compactness}] [ant: {dispersion}, {distribution}]

Density \Den"si*ty\ (d[e^]n"s[i^]*t[y^]), n. [L. densitas; cf.
F. densit['e].]
1. The quality of being dense, close, or thick; compactness;
-- opposed to {rarity}.
[1913 Webster]

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.
[1913 Webster]

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.
[1913 Webster]

3. (Photog.) Depth of shade. --Abney.
[1913 Webster]

  • Density - Wikipedia
    Density is an intensive property in that increasing the amount of a substance does not increase its density; rather it increases its mass Other conceptually comparable quantities or ratios include specific density, relative density (specific gravity), and specific weight
  • Density | Definition, Symbol, Units, Formula, Facts | Britannica
    Density, mass per unit volume of a substance The formula for density is d=M V, where d is density, M is mass, and V is volume Density is commonly expressed in units of gram per cubic centimeter For example, the density of water is 1 gram per cubic centimeter
  • Density Definition in Science
    Density describes how much matter is packed into a given amount of space A substance with high density contains a large amount of mass in a small volume, while a substance with low density contains less mass in the same volume
  • Density - GeeksforGeeks
    Density is a fundamental physical property that measures how much mass is contained within a given volume of a substance In other words, it quantifies how tightly packed the matter in a substance is
  • Density | Volume • Mass • Density | PhET Simulations
    Interact with blocks of different materials, including a custom option by modifying their mass and volume, to explore the effect on the density and discover the conditions for sinking or floating in water
  • 1. 5: Density - Chemistry LibreTexts
    Density is a physical property that is defined as a substance’s mass divided by its volume: Density is usually a measured property of a substance Notice that density is defined in terms of two dissimilar units, mass and volume That means that density overall has derived units, just like velocity
  • Density Formula - How To Calculate Density - The Calculator Site
    To calculate density, you divide the mass by the volume: Density = Mass ÷ Volume Density is often written in mathematics as the symbol p or D Mass can be written as m, and volume can be written as V So if you want to be fancy, the formula looks like this: ρ = m V
  • What is density? - howengineeringworks. com
    Density is the mass per unit volume of a substance and indicates how tightly matter is packed It helps explain why objects float or sink, why some materials feel heavier, and how heat and pressure affect matter
  • Lesson 3. 1: What is Density? - American Chemical Society
    The density of a substance is the relationship between the mass of the substance and how much space it takes up (volume) The mass of atoms, their size, and how they are arranged determine the density of a substance
  • What Is Density? Why Objects Sink or Float
    Density and Floating in Other Liquids It’s not just water that has a density— all fluids do And different liquids have different densities, which affects how objects behave when placed in them For example, the Dead Sea has such a high salt content that it is denser than regular seawater
