Solution
An endothermic process is one that absorbs heat from its surroundings.
a) Burning wax is an exothermic process because it releases heat. b) Evaporating water is an endothermic process because it absorbs heat to change from liquid to gas. c) Melting wax is also an endothermic process because it absorbs heat to change from solid to liquid. d) Roasting a marshmallow is an exothermic process because it releases heat.
So, the correct answer is b, c, and d.
