Difference between Diffusion and Effusion

Whereas some quantity of gas is released in a large area from a small area with some low pressure, in which the gas either effuses or diffuses. The primary dissimilarity among diffusion and effusion is the interrupt which filters the gas as it runs among the two volumes.
Diffusion:
Diffusion is a process of particles going into the area of high to the low concentration. The rate of this movement is an act of particle size, temperature, and medium viscosity. There are a number of molecules or atoms in the gas, which are in regular quick motion, in which randomness occurs with many collisions with each other and container walls.
Effusion:
Not only does gaseous particle travel with kinetic energy which is high, since their little size empowers them to travel through small openings also; This process is recognized as an effusion. For the occurrence of effusion, the molecules have greater than the diameter of the hole. The hole of the opening should be smaller than the free path since the gas can be back and forward through the hole.
