The most conducive surface for dropwise condensation to occur is the _____________ surface?
Correct answer: A. Oily
- A. Oily
- B. Coated
- C. Glazed & polished
- D. Smooth
Explanation
Dropwise condensation is promoted by a non-wetting surface, and an oily surface helps condensate form separate droplets rather than a continuous film. A smooth or polished surface alone does not ensure this non-wetting behaviour.
