WebRadiation laws Blackbody radiation Any substance (solid, liquid or gas) emits radiation according to its absolute temperature, measured in units of Kelvin (K = oC + 273.15). The efficiency at which radiation is emitted varies with the substance. However, at any temperature, there is an upper limit to how much radiation can be emitted.
