Question

A single container wherein the enrichment process takes place through gaseous diffusion is called:
(A) Divider
(B) Diffuser
(C) Stalk
(D) Rotator

Answer 1

Hint: This single container allows the lighter molecules to pass through it more easily and the heavier molecules are depleted by it. Diffusion is a process in which the particles of gases are spread in the open space.

Complete step by step solution:
- We can see that here gaseous diffusion is taking place. The gaseous diffusion is actually based on Graham’s law.
- Graham’s law states that the rate of effusion of a gas is inversely proportional to the square root of the molecular mass of the gas.
- So, we can say that if a mixture of gas has two gases, when allowed to pass through a semipermeable membrane, we can see that both gases will behave differently. The gas which has lighter molecules, will pass out the container more rapidly.
- The gas which has heavier molecules will pass through the membrane in very less amounts. So, as a result, we can see that the gas leaving the container will be enriched with lighter molecules. The residual gas will be somewhat depleted.
- The single container where the enrichment process takes place through the gaseous diffusion process is called a diffuser.

Therefore we can conclude that the correct answer of this question is (B) Diffuser.

Note: With this gaseous diffusion, the diffuser helps us to separate the isotopes of certain elements. We know that the isotopes of the elements do not have the same weights and so that some will be lighter and the other will be heavier. So, we can separate them.
