With increase in the distance between the heat source and the object receiving the heat, the radiation heat transfer ?
Correct answer: A. Decreases
- A. Decreases
- B. Increases
- C. Increases exponentially
- D. Remain unaffected
Explanation
Radiation intensity decreases as the source-receiver distance increases, following an inverse-square relationship for a point source. Therefore, the heat transfer decreases rather than increases.
