What Does Effusion Mean?

According to chemistry, effusion basically is the procedure where separate molecules pass through a hole without conflict.

This will take place if the width of the hole is some what lesser than the mean free path of the molecules. On the basis of the Graham's law, the pace at which gasses effuse normally depends on their molecular mass. Gases which have very low molecular mass will effuse more rapidly than gases which have higher molecular mass. Normally for two gases which have similar temperature, and consequently having the similar kinetic energy, the standard molecular velocity of each gas can be found applying the equations E=(1/2)mv2.

This will consequent in extra molecules passing through the hole per unit time, hence a balloon which is filled with low molecular weight hydrogen will deflate, if kept aside for some amount of time.

The term Effusion is used in Chemistry. It is known as the processes where various individual molecules flow into a hole without colliding in to each other. This process will only occur if the diameter of the hole is smaller than the mean free path of the molecules. The law of Grahams states that the rate at which gases are effused depends on the molecular weight.

According to the law, lighter molecules will have more speed. Due to this the number of molecules passing through the hole will increase in per unit time. One of the most common examples for this can be seen; a balloon that is filled with hydrogen molecules will deflate much quickly then the one filled with heavier molecules of oxygen.

This is procedure where separate molecules pass through a hole without conflict.
