The characteristic radiation from a hot body. Its spectral properties are determined by the body's temperature.
Radiation from an object due to thermal energy
the electromagnetic radiation that would be radiated from an ideal black body; the distribution of energy in the radiated spectrum of a black body depends only on temperature and is determined by Planck's radiation law
a continuous emission spectrum produced by many small energy transitions (electronic and vibrational) in a solid when heated. Most emission is in the IR part of the EM spectrum but moves further into the visible (and UV) with increasing temperature.
The radiation of heat from a body with an emissivity of 1. The amount of power radiated is proportional to the temperature (in Kelvin) to the fourth power. The proportionality constant is the Stephan-Boltzman constant.
The electromagnetic radiation emitted by an ideal blackbody adhering to the radiation laws; it is the theoretical maximum amount of electromagnetic radiation of all wavelengths that can be emitted by a body at a given temperature.
Radiation emitted by a blackbody (the intensity depends on temperature).
Any physical body absorbs and emits electromagnetic radiation when its temperature is above absolute zero. Planck's law determines the radiant flux of a body at a specific wavelength. In atmospheric chemistry, the calculation involving the earth's blackbody radiation shows that the earth's surface temperature would be below the freezing point of water if it did not have an atmosphere which absorbed some of the outgoing radiation.

The electromagnetic radiation emitted by an ideal blackbody; it is the theoretical maximum amount of radiant energy of all wavelengths that can be emitted by a body at a given temperature. The spectral distribution of blackbody radiation is described by Planck's law and related radiation laws.
Radiation, especially its spectral distribution, from an ideal blackbody emitter.
