Question

The dispersed phase and dispersion medium of fog respectively are?

• A. Solid, liquid
• B. Liquid, liquid
• C. Liquid, gas
• D. Gas, liquid

Answer 1

The correct option is C

Liquid, gas

The explanation for the correct option:

Option(C): Liquid, gas

• The discontinuous phase of dispersion that distributes throughout the dispersion medium is known as the dispersed phase.
• Whereas the medium in which the colloidal particles are being distributed is known as the medium of dispersion.
• The dispersed phase and dispersion medium of fog respectively are known as liquid and gas.
• Here the fog as a colloid is an example of liquid aerosol.

The explanation for the incorrect option:

Option(A): Solid, liquid

• Solid, and liquid are not the respective dispersed phase and dispersion medium of fog.
• Thus, the given option is the incorrect one.

Option(B): Liquid, liquid

• Liquid and liquid are not considered as the respective dispersed phase and dispersion medium of fog.
• Hence, the given option does not coincide with the correct concept.

Option(D): Gas, liquid

• Gas and liquid are not the respective dispersed phase and dispersion medium of fog.
• Hence, the given option does not represent the correct concept.

Hence, the dispersed phase and dispersion medium of fog respectively are Liquid, and gas, option (C) is the correct answer.
