The Stefan-Boltzmann law is
#A# = surface area (#m^2# )#sigma# = Stefan-Boltzmann (#~5.67*10^-8Wm^-2K^-4# )#T# = surface temperature (#K# )
This law is used to find the luminosity (the rate of energy released), for an object given its surface temperature. This law assumes the body acts as a black-body radiator (an object that emits energy from the entire EM spectrum)
For a given object with a constant surface area, the Stefan-Boltzmann law says that luminosity is proportional to the temperature raised to the fourth power.
