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… Web= 1.5%; Earth = (78/271) = 28.8%, Mars = (2.7/271)= 1.0%, Titan = (97/271)=35.8%, Pluto=(90/271)=33.2%.

WebJan 21, 2013 · The troposphere starts at the Earth's surface and extends 8 to 14.5 kilometers high (5 to 9 miles). This part of the atmosphere is the most dense. Almost all weather is in this region. Stratosphere. The stratosphere starts just above the troposphere and extends to 50 kilometers (31 miles) high. The ozone layer, which absorbs and … WebMars, the next largest and farthest from the sun, has a very tenuous atmosphere that is mostly CO 2 and an average temperature close to or just a bit above that predicted by the simple black body model. Venus is closest in size to Earth, but has an atmosphere that is much denser than Earth’s.
WebAir density can be defined as the number of air molecules per unit volume (number density). Near sea level there are about 2.7x10 19 molecules per cm 3 (cubic centimeter) or 4.4x10 20 molecules per inch 3 (cubic inch). Air molecules are held near the earth by gravity. In other words, air has weight.
