English
Etymology
Borrowed from Middle French densité or Latin densitas.
Noun
density (countable and uncountable, plural densities)
- (physics) A measure of the mass of matter contained by a unit volume.
- 2013 May-June, Kevin Heng, “Why Does Nature Form Exoplanets Easily?”, in American Scientist, volume 101, number 3, page 184:
- In the past two years, NASA’s Kepler Space Telescope has located nearly 3,000 exoplanet candidates ranging from sub-Earth-sized minions to gas giants that dwarf our own Jupiter. Their densities range from that of styrofoam to iron.
- 2018 October 3, Youn Young Shim; Rana Mustafa; Jianheng Shen; Kornsulee Ratanapariyanuch; Martin J. T. Reaney, “Composition and Properties of Aquafaba: Water Recovered from Commercially Canned Chickpeas”, in Journal of Visualized Experiments, volume 132, DOI: , PMID 29553544:
- Aquafaba was recovered from 10 commercial canned chickpea products and correlations among aquafaba composition, density, viscosity and foaming properties were investigated. Proton NMR was used to characterize aquafaba composition before and after ultrafiltration through membranes with different molecular weight cut offs (MWCOs of 3, 10, or 50 kDa).
- The ratio of one quantity to another quantity.
- 2010, Neil Gillespie, Discover Your Core, Then Go for More, page 42:
- Let's say you get a new customer across town and you don't have any other customers over there. You still need to be competitive with price, but it costs too much money to send crews or a serviceman to one account across town. You need to get more customers over there for margins to exceed the costs of going over there. Once you hit a certain density, you're in the black.
- The number of particles per unit volume of a specified volume can be considered to be the particle density for the specified volume.
- The probability that an event will occur, as a function of some observed variable.
