which represents an endothermic reaction?\nwood burning in a fire\nsplitting a gas molecule\nusing a heat pack on an injury\ntnt exploding

Answer

Brief Explanations:

An endothermic reaction absorbs heat from the surroundings. Wood burning, using a heat - pack, and TNT exploding release heat (exothermic). Splitting a gas molecule requires energy input (absorbs heat), making it endothermic.

Answer:

splitting a gas molecule
