relation between the amount of energy emitted by a unit area on an object producing a thermal spectrum and its temperature: energy in Joules emitted by one square meter = 5.67× 10-8 × temperature4. The temperature is in Kelvin.

A formula from which the rate at which a blackbody radiates energy can be computed; the total rate of energy emission from a unit area of a blackbody is proportional to the fourth power of its absolute temperature.

A thermodynamics law that illustrates emission rates of radian energy from the surface of a body.

a mathematical relationship for electromagnetic radiation that states the irrandiance of a blackbody is proportional to the fourth power of the absolute temperature of the blackbody

Describes the total rate of energy emission per unit surface area. The Stefan-Boltzmann Law is the spectrally integrated form of Planck's Law (integrated over all wavelengths). This result takes the form E=sT4, where E is the rate of energy emitted per unit area, T is the absolute temperature in Kelvin, and s is a constant.
