The absolute temperatureThe square of the temperature (T²)The fifth power of the temperature (T⁵)The fourth power of the temperature (T⁴)The reciprocal of the temperature (1/T)

Explanation

Stefan's law states that the total radiation emitted by a black body per unit area per second is proportional to the fourth power of its absolute temperature, represented as T⁴.
