    		 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.
