According to Stefan's law, the total radiation from a black body per second per unit area is proportional to
A
Absolute temperature
B
T<sup>2</sup>
C
T<sup>5</sup>
D
T
Correct Answer: T
The Stefan–Boltzmann law describes the power radiated from a black body in terms of its temperature.Specifically, the Stefan–Boltzmann law states that the total energy radiated per unit surface area of a black body across all wavelengths per unit time is directly proportional to the fourth power of the black body's temperature.
