Composition and properties of air
WebThe density of air or atmospheric density, denoted ρ, is the mass per unit volume of Earth's atmosphere.Air density, like air pressure, decreases with increasing altitude. It also changes with variation in atmospheric pressure, temperature and humidity.At 101.325 kPa (abs) and 20 °C (68 °F), air has a density of approximately 1.204 kg/m 3 (0.0752 lb/cu ft), … WebAir is composed of many elements such as gases, water vapours, dust particles, and many more. The earth’s atmosphere is filled with air. The air composition has 78% of nitrogen, 21% of oxygen and other trace elements. Air also has water vapour and dust particles. Air is an indispensable resource for the respiration of all living organisms.
