WebThe mass of the Earth is found to be 6 sextillion, 587 quintillion short tons (or 5.98 × 10 21 metric tons). Since the Earth is a sphere, the formula 4/3πr 3 is used to find the volume. The volume of the Earth is considered to be 1.08 × 10 12 km 3 (or 2.5988 × 10 11 miles 3 ). I also calculated numbers for the density of the Earth. 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 approximately 1.204 kg/m (0.0752 lb/cu ft), according to the International Standard Atmosphere (ISA). At 101.325 kPa (abs) and 15 °C (59 °F), air has a density of approx…

WebDec 22, 2024 · The density (more precisely, the volumetric mass density) of a substance is its mass per unit volume (denoted in kg/m 3 ). It is a unique physical property of an object that shows how tightly matter is packed together that object. Solid materials, such as iron and platinum, have densely packed particles. WebPure, dry air has a density of 1.293 kg m−3 at a temperature of 273 K and a pressure of 101.325 kPa. Apart from the variability of water vapor, the composition of air is essentially constant to an altitude of at least 50 km. You Might Also Be Interested In ts await 类型
