How Do Air Particles Travel?
Air Particles In order to understand how air particles move, it is first necessary to understand what air is made of and how it acts. While the exact composition of air differs at any given place and time, the components generally fall under two different categories: what we think of as the air itself and particles floating through the air. Air itself is composed of a mixture of atoms, mostly nitrogen and oxygen, with many other elements also present. These atoms compose most of the atmosphere and are always present, literally the fluid through which all other particles travel. The other category includes the larger particles that float through the air, heavier than the atoms but still very small, including water vapor and dust. Larger Particles These other particles can again be divided into two categories: coarse and fine. Coarse particles are the largest that can stay afloat and the most visible to humans, such as smoke, pollen, and dust. Fine particles are much smaller, often only
