Web1. All atoms and molecules in the Earth's atmosphere are held by the gravitational force of the planet. The force decreases by 1/(distance)2 so the particles are held less tightly as the distance between them and the Earth (altitude) increases. 2. The gas density, that is the mass of gas particles in every liter of volume, decreases as the altitude WebApr 12, 2024 · Soot particles that are more reactive may deposit more quickly onto surfaces, which can impact air quality and human health in urban areas. The presence of these functional groups on the surface of the soot particles is influenced by a number of factors, including the combustion conditions under which the soot particles are formed.
