Understand the difference between diffusion and effusion of a gas and find out which is faster. read more
The main difference between diffusion and effusion is the barrier between the two volumes. Effusion occurs when there is a barrier with one or many small holes that prevent the gas to expand into the new volume unless a gas molecule happens to travel through the hole. read more
Diffusion vs. Effusion Both diffusion and effusion are terms in chemistry and describe the properties of gases. Whereas diffusion talks about ability of gases to mix with each other, effusion describes different rates at which gases pass through a pinhole from an area of high pressure to an area of low pressure. read more
Diffusion refers to the expansion of gas to fit a larger volume; effusion refers to the passage of the gas through a small hole to fill the larger volume. In diffusion the barrier between the gas and the container in which it is to expand is either non-existent or has an aperture larger than the mean free path of the gas molecules, allowing the gas to move through freely. read more
