Nothing has heat. Things can have a temperature. They can have a thermal energy but they canât have heat. Heat is really the transfer of thermal energy. Or, in other words, the movement of thermal energy from one object to another. If you put an ice cube in a glass of lemonade, the ice cube melts.
In the case of a black object, the reflected component is absent, leaving only the temperature-dependent part. Thus, for a perfectly black object, the light coming off of it is perfectly described by the blackbody curve. Hence the name.
