Question

A process used to separate liquid solutions is _____. diffusion adhesion distillation cohesion

Answer 1

Answer: Option (c) is the correct answer.

Explanation:

When two different liquids of two different boiling point are mixed together then they can be separated by heating. Liquid with low boiling point will evaporate readily upon heating and when its vapors condense then it will be separated from the solution.

This process of separation is known as distillation.

Diffusion is the ability of a substance or liquid to spread into another liquid.

When non-similar particles cling to each other then it is known as adhesion.

When similar particles cling to each other then it is known as cohesion.

Hence, we can conclude that a process used to separate liquid solutions is diffusion.

Answer 2

The process is known as distillation, because adhesion is the force between molecules of different liquids i.e mercury and water while cohesion is the force that exists between molecules of the same liquids i.e mercury and mercury or water and water. Diffusion is just the movement of gaseous molecules from area of higher concentration to areas of lower concentration through a semi-permeable membrane.
