minute.

8. Make a note of when the ice melts and when the water begins boiling.

Data:

Graph your data. Remember to label and title the graph.

What is the best kind of graph to use? ___________________________________

Why? ______________________________________________________________

Label these 5 areas on your graph: solid (S), liquid (L), gas (G), freezing point/melting point FP/MP and

condensation/boiling point (CP/BP).

Use map pencils to color the following parts of the line on your graph: slowest molecular motion (in one color), fastest

molecular motion (in a different color). Make a key to distinguish the colors you used for labeling.
