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.
