At 101.325 kPa (abs) and 15 °C (59 °F), air has a density of approximately 1.225 kg/m 3 (0.0765 lb/cu ft ), which is about 1⁄800 that of water, according to the International Standard Atmosphere (ISA). [citation needed] Pure liquid water is 1,000 kg/m 3 (62 lb/cu ft). See more 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 … 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. This occurs because the molar mass of … See more • Air • Atmospheric drag • Lighter than air • Density • Atmosphere of Earth • International Standard Atmosphere 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.

Calculate the height of a cube made of Oak Wood, which weighs one metric ton. Solution: Density is defined as the mass per unit volume. It is mathematically defined as mass divided by volume: ρ = m/V. As the volume of a cube is the third power of its sides (V = a 3), the height of this cube can be calculated:

Density of atmosphere with height

In general, air pressure and density decrease with altitude in the atmosphere. However, the temperature has a more complicated profile with altitude, and may remain relatively constant or even increase with altitude in some regions (see the temperature section, below). Because the general pattern of the temperature/altitude profile, or lapse rate, is constant and measurable by mea… WebApr 11, 2024 · The structural complexity of forest fuels was assessed by calculating the LiDAR Height Diversity Index (LHDI) with regard to the distribution and vertical diversity of the vegetation with the highest values of LHDI, which corresponded to Pinus spp.–evergreen (2.56), Quercus suber (2.54), and Pinus mixed (2.49) forests, with the minimum being ...
