True or False. If you double the temperature of a blackbody, it will emit double the energy.

true

Explanation:

All objects with a temperature above absolute zero (0 K, - 273.15 oC) emit energy in the form of electromagnetic radiation.

A blackbody is a theoretical or model body which absorbs all radiation falling on it, reflecting or transmitting none. It is a hypothetical object which is a "perfect" absorber and a "perfect" emitter of radiation over all wavelengths.

The spectral distribution of the thermal energy radiated by a blackbody (i. e. the pattern of the intensity of the radiation over a range of wavelengths or frequencies) depends only on its temperature.
