Smoke and fog are both _____. They have the same _____ but different _____.​

• A. Aerosols, Dispersed phase, Dispersion medium​
• B. Aerosol, Dispersion medium, Dispersed phase​
• C. Sols, Dispersed phase, Dispersion medium​
• D. Sols, Dispersion medium, Dispersed phase​

Answer 1

The correct option is B Aerosol, Dispersion medium, Dispersed phase​

Smoke is made up of dust and soot mixed with the air which is a mixture of solid and gas, respectively. Whereas fog is made up of mixture of water droplets and air, which are liquid and gas, respectively. Thus both smoke and fog are both Aerosols. They have the same Dispersion Medium which is gas but have different Dispersed Phase i.e., solid and liquid, respectively.​
