What does endothermic describe?

  1. Self heating

  2. Requires added heat source

  3. Processes at room temperature

  4. Requires no external heat

The correct answer is: Requires added heat source

Endothermic means that a process requires added heat in order to take place. Self heating (A) implies that the process generates its own heat, which is not what endothermic describes. Processes at room temperature (C) may or may not be endothermic, but it is not a defining characteristic of endothermic reactions. Requires no external heat (D) is incorrect because, as stated before, endothermic processes require added heat in order to occur.
