WebFigure 2. Diffusion occurs when gas molecules disperse throughout a container. Effusion occurs when a gas passes through an opening that is smaller than the mean free path of the particles, that is, the average distance traveled between collisions. Effectively, this means that only one particle passes through at a time. WebFeb 17, 2024 · The pressure exerted by a gas is the result of the innumerable impacts of the molecules on the container walls and appears steady to human senses because so many collisions occur each second …

The pleural cavity, also called the chest of the thoracic cavity, is the space above ... In physics and chemistry, effusion is the process in which a gas escapes from a container through a hole of diameter considerably smaller than the mean free path of the molecules. Such a hole is often described as a pinhole and the escape of the gas is due to the pressure difference between the container … See more The word effusion derives from the Latin word, effundo, which means "shed, pour forth, pour out, utter, lavish, waste." See more According to the kinetic theory of gases, the kinetic energy for a gas at a temperature $${\displaystyle T}$$ is $${\displaystyle {\frac {1}{2}}mv_{\rm {rms}}^{2}={\frac {3}{2}}k_{\rm {B}}T}$$ where $${\displaystyle m}$$ is the mass of one molecule, See more The Knudsen effusion cell is used to measure the vapor pressures of a solid with very low vapor pressure. Such a solid forms a vapor at … See more At constant pressure and temperature, the root-mean-square speed and therefore the effusion rate are inversely proportional to the square root of the molecular weight.
