...intensity of radiation of a black body is * = «.fl* ....... (48) ie the total intensity of emission of a black body is proportional to the fourth power of its absolute temperature. This law, which Stefan * first discovered experimentally and Boltzmann deduced theoretically in a way...

...BY EDGAR BUCKINGHAM. BOLTZMANN'S thermodynamic deduction of Stefan's law, that the total temperature radiation of a black body is proportional to the fourth power of the absolute temperature, is very concise ; and it seems to me that the same thing may be done a little...

...100 ohms. The diameter of the stop wic was 1 G mm. in all experiments. Assuming Stefan's law, that the total radiation of a black body is proportional to the fourth power of the absolute temperature, we have the equation 3 = <r(64-2901) ;l when 8 is the deviation of the needle,...

...a practical application of Stefan's law, which is to the effect that the radiation of an absolutely black body is proportional to the fourth power of its absolute temperature. Kirchoff has proved that the interior of an inclosure of which the walls are at a uniform temperature...

...research, succeeded in establishing the physical law that the total energy-of radiation from a hot body is proportional to the fourth power of its absolute temperature. The research from which this law was deduced is discussed by Waidner and Burgos in Bulletin Xo. 2 of the...

...based, in principle, on Stefan's law, which runs to the effect that the radiation from an absolutely black body is proportional to the fourth power of its absolute temperature. By an " absolutely black body " is meant, in this case, one which receives and retains all the heat...

...one-third the radiation energy per unit of volume, deduce the law that the radiation of a perfectly black body is proportional to the fourth power of its absolute temperature. 2. — Show how to determine the maximum of work which can be obtained from a perfectly isolated system....
