Question

Quizplus · Accepted Answer

The rate at which an object radiates thermal energy is proportional to the fourth power of its absolute temperature, according to the Stefan-Boltzmann law. Therefore, if the absolute temperature is tripled, the rate of radiation increases by $3^4 = 81$ times.

If the Absolute Temperature of an Object Is Tripled,the Rate
