Difference Between Effusion And Diffusion

6 Differences Between Effusion And Diffusion

S.NO.	Effusion	Diffusion
1.	Effusion is the process of a gas escaping through a small opening or hole.	Diffusion is the movement of a gas or substance from an area of high concentration to an area of low concentration.
2.	Effusion is driven by the pressure difference between the two sides of the opening or hole.	Diffusion is driven by the concentration gradient between the two areas.
3.	Effusion is a process that occurs in a closed system.	Diffusion can occur in both closed and open systems.
4.	Effusion occurs at a faster rate when the gas is at a higher temperature and when the size of the opening or hole is smaller.	Diffusion occurs at a faster rate when the concentration gradient is greater and when the distance between the two areas is smaller.
5.	Effusion occurs when a gas is escaping from a container or system.	Diffusion occurs when a gas or substance is moving within a container or system.
6.	Effusion is used to measure the molecular weight of a gas.	Diffusion is used to study the movement of gases and substances in a variety of contexts, such as in cells, in the atmosphere, and in industrial processes.
