What is the density of air?

Answer 1

The density of air, is the mass per unit volume of Earth's atmosphere. In the SI system it is measured as the number of kilograms of air in a cubic meter (kg/m3). At sea level and at 20 °C dry air has a density of approximately 1.2 kg/m3. varying with pressure and temperature. Air density and air pressure decrease with increasing altitude.

Answer 2

The Density of air is 1.29 g/L, while nitrogen is about 1.25 g/L. Nitrogen is a tad lighter than air. These data are the ones quoted all the time with the understanding that the values are at sea level or normal level. Note that as you go higher up in altitude up to outer space the density decreases to the point that there are hardly any oxygen available to support human life.

Note that AIR is a HOMOGENEOUS mixture consisting of about 78% nitrogen and 21% oxygen and the rest other elements and Water vapor.

Answer 3

Air Density@20°C: 1.2 kg/m³

(Imperial @ 60°F: 0.078 lb/ft³)

Answer 4

Depends on the temperature and altitude.
Standard temp. (52f) at sea level =barometrric pressure of air is 29.92hg
