Effusion is the process by which gas particles escape from a container through a small hole or opening into a vacuum or a lower-pressure area. This process occurs without any significant collision of particles between them or with particles of the surrounding medium. Effusion is described by Graham's law, which states that the rate of effusion of a gas is inversely proportional to the square root of its molar mass. This means lighter gases will effuse faster than heavier gases.
