What is the average free way?
The average free path is an average length that the particle can travel in an environment before colliding, absorbing or reacting with a different particle. This term is often used to discuss gas behavior, but also applied in the fields of sound and light. You could calculate the average free path of the player in the football game. On a relative basis of oxygen molecule, it travels much further in the air than it collides than a footballer. The volume of the gas is the volume of the container. The gases are easily compressed, widespread and mixed. Gases are often invisible due to their low concentration of mass per unit volume, or, differently, a long average free path of their molecules. The value of the path is necessarily the result of models, because there is no way to measure or monitor one molecule. Scientists look at observable parameters such as volume, temperature and pressure, as well as the size of the gas and gas molecules and gas concentrations to model the behavior of the gas molecule and derive the calculated values.
air molecules, under standard conditions of 1 atmosphere (£ 14.7 per square inch), 0Deg; C (32 ° F) and the given molecular diameter of 0.3 nanometers, nm, (1.2 x 10-8 inches), calculate the average free path 93 nm (3.6 x 10 to 6 inches). The average molecular separation is calculated at 3.3 nm (1.3 x10-7 inches). If footballers were as agile as atoms, their average free road would be about 800 feet (244 meters), based on the American football field. Of course, footballers are not evenly distracted about the fields, as well as the gas gas molecules.
In sound studies, the average free path concerns the average distance that the beam travels before it bounces from an obstacle. This calculation is important in acoustics and depends on the volume of the room and the overall surface area of the walls, ceiling and floor of the room. Acoustic studies, although complicated, are quantifiable because the speed of sound waves can be accurately measuredthe conditions.
Studies of light scattering by gases or liquids use the average free path calculations. These are defined as an average distance traveled by a photon before a scattering event due to a collision or a photon absorption. Calculations can be used to determine things such as water and concentration of various solutions. The tea drinkers observe the average path without distraction to determine whether their tea has been sufficiently cooked.
