Answer:
radiation
Explanation:
Heat transfer is the process of propagating heat in different media. Three types of heat transfer are known: conduction, convection and radiation
The transfer by radiation is given at a distance. In fact, at any distance, as long as there is nothing that absorbs that energy along the way, and does not need a means to propagate.
Endothermic you can see this by putting a thermometer in a glass or warm water, adding an ice cube and watching the temperature go down as the ice melts
