Therefore, a third model of the flow can be a microscopic approach wherein the fundamental laws of nature are applied directly to the atoms and molecules, using suitable statistical averaging to define the resulting fluid properties. This approach is in the purview of kinetic theory, which is a very

Lighter Than Air: Why Do Balloons Float?
kicp-workshops.uchicago.eduWe are so accustomed to swimming in air we forget that it is made of atoms and molecules (mostly nitrogen molecules, N 2), that have mass. This fact means that when the air molecules are displaced by an object, they push back with a buoyant force equal to the mass of the volume air pushed aside.
