Density
01
densitet, massvolym
(physics) the degree to which a substance is compacted, measured by dividing its mass by its volume
Exempel
The density of water is approximately 1 gram per cubic centimeter ( g / cm³ ).
Vattnets densitet är ungefär 1 gram per kubikcentimeter (g/cm³).
Air has a much lower density compared to water, which is why objects float in water but fall through air.
Luft har en mycket lägre densitet jämfört med vatten, vilket är anledningen till att föremål flyter i vatten men faller genom luft.
02
densitet, koncentration
the spatial property of having elements packed closely together, typically expressed as the number of units per given area or volume
Exempel
Urban planners analyze population density to determine where to build new transit lines.
Stadsplanerare analyserar befolkningstätheten för att avgöra var nya transportlinjer ska byggas.
The forest survey measured tree density at 550 specimens per hectare.
Skogsundersökningen mätte trädens densitet till 550 exemplar per hektar.
03
the degree to which light is blocked or absorbed by a photographic filter or film, usually measured in stops or optical density units
Exempel
The photographer adjusted the filter density to reduce glare.
The technician calibrated the density of the photographic plate.
