Explanation:
Rate of Condensation:
- The rate of condensation is the process by which water vapor in the air transforms into liquid water.
- Condensation occurs when the air cools down to the point where it cannot hold all of the water vapor it contains.
Rusty Surface vs. Polished Surface:
- Rusty surfaces have irregularities and roughness which provide more surface area for water molecules to condense on.
- Polished surfaces, on the other hand, are smooth and promote drop-wise condensation where water droplets form on the surface and roll off instead of wetting the surface.
Relation between Rate of Condensation and Surface Type:
- The rate of condensation over a rusty surface is less than that over a polished surface because the polished surface promotes drop-wise condensation.
- Drop-wise condensation does not wet the surface, allowing for a higher rate of condensation compared to a rusty surface where the water molecules can adhere to the rough surface.
Therefore, both Assertion (A) and Reason (R) are individually true, and Reason (R) is the correct explanation of Assertion (A).
