Question

In which situation will screening be used to separate a mixture?

A. if the mixture is a solid suspended in a gas
B. if the components have different boiling points
C. if the mixture is a solid dissolved in a liquid
D. if the components have different colors

Answer 1

Hello!

I believe the answer is

A) if the mixture is a solid suspended in a gas

Answer 2

Answer: Option (A) is the correct answer.

Explanation:

When granular solids are separated out according to their size then this process of separation is known as screening.

So, when a solid substance dissolves in a liquid then its molecules will dissociate into ions. Therefore, its particles cannot be separated out by screening.

Therefore, when solid particles are suspended in a gas then they can be separated out easily through the process of screening.

Thus, we can conclude that in a situation where the mixture is a solid suspended in a gas then screening be used to separate a mixture.
