Quizplus · Accepted Answer

The slope of segment AB corresponds to the heat capacity of the solid because this segment represents the phase where the substance is being heated as a solid, and its temperature is increasing without a phase change. The slope here indicates how much heat is required to raise the temperature of the solid, which is the definition of heat capacity.
