Heat transfer by radiation between two bodies at T1 & T2 and in an ambient temperature of Ta°C depends on_____________?
Correct answer: C. None of these
- A. T1 - T2
- B. T1 - Ta
- C. None of these
- D. T2 - Ta
Explanation
Radiative heat exchange depends on the fourth powers of absolute temperatures, such as T₁⁴ − T₂⁴, rather than on any simple temperature difference listed. The ambient temperature may affect the surroundings exchange, but none of options gives the required fourth-power relation.
