The correct Answer is:
To determine the dispersed phase and dispersion medium for fog, we can follow these steps: ### Step 1: Understand the Definitions - **Dispersed Phase**: This is the phase that consists of the finely divided particles that are distributed throughout another substance. It is usually present in a smaller amount, similar to a solute in a solution. - **Dispersion Medium**: This is the medium in which the dispersed phase is distributed. It is generally present in a larger amount, akin to a solvent in a solution. ### Step 2: Identify the Components of Fog - Fog is a colloidal system where tiny water droplets are suspended in air. - In this case, the water droplets are the particles that are dispersed, while the air acts as the medium in which these droplets are suspended. ### Step 3: Classify the Phases - **Dispersed Phase**: The water droplets in fog are the dispersed phase because they are the smaller component that is distributed throughout the medium. - **Dispersion Medium**: The air in which the water droplets are suspended is the dispersion medium because it is present in a larger quantity. ### Conclusion - Therefore, for fog: - **Dispersed Phase**: Liquid (water droplets) - **Dispersion Medium**: Gas (air) ### Final Answer - Dispersed phase for fog: Liquid (water droplets) - Dispersion medium for fog: Gas (air) ---
