Heat transfer by radiation between two bodies at T1 & T2 and in an ambient temperature of Ta°C depends on

Question

Quizplus · Accepted Answer

Heat transfer by radiation depends on the fourth power of the absolute temperatures of the bodies involved, not directly on the differences in temperatures as stated in options A, B, or C. The correct relationship is given by the Stefan-Boltzmann law, which does not simplify to any of the temperature differences listed.
