What temperature increase is necessary to increase the power radiated from an object by a factor of 8?
A)8 K
B)2 K
C)100%
D)about 68%

Question

Quizplus · Accepted Answer

The power radiated by an object is proportional to the fourth power of its temperature (Stefan-Boltzmann Law). To increase the power by a factor of 8, the temperature must increase by the fourth root of 8, which is approximately 1.68, or about 68%.
