Which of the following phenomenon will exhibit the minimum heat transfer ?
Correct answer: A. Conduction in air
- A. Conduction in air
- B. Forced convection in air
- C. Free convection in air
- D. Boiling
Explanation
Still air has very low thermal conductivity, so conduction through air provides less heat transfer than either natural or forced convection. Boiling generally gives the highest coefficient among these choices.
