what statement best explains the plateau seen in the cooling curve of naphthalene?\na the energy of the system decreases.\nb the temperature of the system increases.\nc the temperature of the system decreases.\nd the energy of the system remains constant.
Answer
Brief Explanations:
During a phase - change (in this case, likely the solid - liquid phase change of naphthalene), the energy is used for the phase transition rather than changing the temperature. So, the temperature remains constant during the plateau, and the energy of the system is being used for the phase - change process, resulting in a constant energy level during that time.
Answer:
D. The energy of the system remains constant.
