Knudsen effusion

effusion">Knudsen effusion is a process that describes how gas molecules escape through small openings or holes into a vacuum. When gas molecules collide with the walls of a tiny opening, some get through while others bounce back. This behavior is influenced by factors like the size of the opening and the speed of the gas molecules. It helps scientists understand gas behavior and is important in various applications, including the design of vacuum systems and studying molecular properties. Essentially, it illustrates how gases can flow and diffuse into lower-pressure areas.
