According to Stefan Boltzmann law, ideal radiators emit radiant energy at a rate proportional to

A Absolute temperature
B Square of temperature
C Fourth power of absolute temperature
D Fourth power of temperature

Correct Answer: Fourth power of absolute temperature

Stefan-Boltzmann law is applicable for radiation it states that the total radiant heat power emitted from a surface is proportional to the fourth power of its absolute temperature. The law applies only to blackbodies, theoretical surfaces that absorb all incident heat radiation.
