Webb26 mars 2016 · You can use the Stefan-Boltzmann constant to measure the amount of heat that is emitted by a blackbody. Physicists have determined that a blackbody is an object that absorbs 100 percent of the radiant energy striking it, and if it’s in equilibrium with its surroundings, it emits all the radiant energy as well.
