Inferring:A student examines a thermometer placed in a can containing a substance that is being heated. The temperature remains the same for several minutes, then it starts to rise.Without looking in the can, how does the student know what is occurring in the car?

Answer 1

I would think that the substance in the can is undergoing a phase change. The temperature remains constant during the phase change but the temperature rises after all of the substance has changed from one phase to another.
