This is a list of countries and dependencies ranked by population density, sorted by inhabitants per square kilometre or square mile. The list includes sovereign states and self-governing dependent territories based upon the ISO standard ISO 3166-1. The list also includes unrecognized but de facto independent countries. The figures in the table ...
The maximum density of a substance is the highest attainable density ... Almost all known substances undergo ... characteristic properties of the solid state of matter.
Arable density (m² per capita) by country. This is a list of countries ordered by physiological density."Arable land" is defined by the UN's Food and Agriculture Organization, the source of "Arable land (hectares per person)" as land under temporary crops (double-cropped areas are counted once), temporary meadows for mowing or for pasture, land under market or kitchen gardens, and land ...
This is an extended version of the energy density table from the main Energy density page: Energy densities table Storage type Specific energy (MJ/kg)
This is a list of countries and territories in Europe by population density.Data are from the United Nations unless otherwise specified. [1] [2]Abkhazia, Georgia and South Ossetia are each bordered on the north by the Greater Caucasus, and may have some territory north of these mountains and thus in Europe by the most common definition.
Since all gases have the same volume per mole at a given temperature and pressure far from their points of liquefaction and solidification (see Perfect gas), and air is about 1 / 5 oxygen (molecular mass 32) and 4 / 5 nitrogen (molecular mass 28), the density of any near-perfect gas relative to air can be obtained to a good ...
Although the arithmetic density is the most common way of measuring population density, several other methods have been developed to provide alternative measures of population density over a specific area. Arithmetic density: The total number of people / area of land; Physiological density: The total population / area of arable land ...
The area density (also known as areal density, surface density, superficial density, areic density, mass thickness, column density, or density thickness) of a two-dimensional object is calculated as the mass per unit area. The SI derived unit is the "kilogram per square metre" (kg·m −2).
