Stefan-Boltzmann law which describes the radiation heat transfer states that, it is proportional to (where, t = temperature in °C T = absolute temperature in ° K) ?
Correct answer: C. T4
- A. t4
- B. 1/t4
- C. T4
- D. 1/T4
Explanation
The Stefan-Boltzmann law states that blackbody emissive power is proportional to the fourth power of absolute temperature, T⁴. Celsius temperature cannot be used because the radiation relation requires a Kelvin scale measured from absolute zero.
