Simulator Instructions -
1. Sketch what the graph created during this experiment looks like.
2. Assuming that the substance being heated starts out as a solid what is its melting point?
3. What is the boiling point of this substance?
4. Circle and label the parts of this graph that show the experimental substance in the solid, liquid and gas phases.
5. Could the substance used in this experiment be water? Why or why not?
