 14 When heat is added to boiling water, its temperature
 A. Increases.
 B. Decreases.
 C. Does not change.
 15 Boiling water does not increase in temperature when additional heat is applied because
 A. The temperature doesn't change in a change of state
 B. Added input energy doesn't increase the water's internal energy
