The energy radiated from a surface Q at absolute temperature T is related as__________________?
Correct answer: D. Q ∝ T4
- A. Q ∝ T2
- B. None of these
- C. Q ∝ T3
- D. Q ∝ T4
Explanation
The Stefan-Boltzmann law states that radiation from an ideal surface varies with the fourth power of absolute temperature, Q proportional to T⁴. Absolute temperature must be used, not Celsius temperature.
