    A student measures the temperature of a system as energy is added to it. The temperature rises linearly and over time begins to level off before reaching a plateau. The student notes that energy continues to be added at a constant rate. Which of the following conclusions must be true based on this information?

     

    A

    The system is not closed, and loses energy to its surroundings.

    B

    The system is undergoing a phase change and thus it plateus.

    C

    The electrons of the system have reached their maximum energy state and cannot be excited any further.

    D

    The scenario is not possible and the student has made a measurement error.
