Question

Quizplus · Accepted Answer

Phase changes B → C and D → E are associated with the heat energy being used up to increase distances between molecules. During phase changes, heat energy is absorbed without changing temperature as the energy is used to break intermolecular bonds and increase the distance between molecules. In phase change B → C, the heat energy is used to break the bonds between solid molecules to form a liquid. In phase change D → E, the heat energy is used to break the bonds between liquid molecules to form a gas. Therefore, choice B is the best answer.
