The Stefan–Boltzmann law describes the power radiated from a blackbody in terms of its temperature and states that the total energy radiated per unit surface area of a black body across all wavelength...The Stefan–Boltzmann law describes the power radiated from a blackbody in terms of its temperature and 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 thermodynamic temperature T.
