What term describes a two-phase system consisting of a finely divided solid dispersed in a solid, liquid, or gas?

• A. Suspension
• B. Granules
• C. Capsule
• D. Syrup

Answer: (A)

A suspension is a two-phase system where finely divided solid particles are dispersed in a continuous phase that can be solid, liquid, or gas. The key idea is that the solid remains as discrete particles and does not dissolve, giving a heterogeneous mixture that may settle over time and needs shaking to redisperse.

This fits the description because the dispersed phase is a finely divided solid, and the surrounding medium can be a solid, a liquid, or a gas, matching the broad sense of a two-phase system. In contrast, a capsule describes encapsulated material, a syrup is a solution where solute is dissolved, and granules are larger clumps of powder, not a distinct two-phase dispersed system.
