WebDensity of Air is dependant on several factors such as relative humidity, temperature, pressure and altitude, etc. Air Pressure is also related to the weight of air i.e. if you stand on heights you will have less air above and therefore the pressure is lower.

WebDensity is the ratio of mass to volume for a material. Units 1000 kg/m 3 = 1000 g/l = 1 g/cm 3 Density of selected materials (~20 °C, 1 atm) Average density of some celestial bodies Density as a general concept. mass density charge density, see charge current density, see current number density, especially in this book… WebHelium, on the other hand, is much lighter than air (nitrogen and oxygen), so that is why a helium-filled balloon goes up. At higher altitudes, the air is thinner (less atoms in the same volume), but the relative amounts of nitrogen and oxygen are the same. This is true until you get about 100km (60 miles) above the surface of the earth. 基礎から学べる材料力学
