Density of air - Wikipedia

The 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 … See more Other things being equal, hotter air is less dense than cooler air and will thus rise through cooler air. This can be seen by using the ideal gas law as an approximation. See more Troposphere To calculate the density of air as a function of altitude, one requires additional parameters. For the … See more • Conversions of density units ρ by Sengpielaudio • Air density and density altitude calculations and by Richard Shelquist See more The addition of water vapor to air (making the air humid) reduces the density of the air, which may at first appear counter-intuitive.
