Producing a heating curve for water is fairly simple. You could place a large sample of ice in a beaker and heat it using a hotplate while recording the temperature every minute. However, in this activity the data has already been collected for you. In this assignment, you will graph and analyze an actual heating curve for water. Then, using the data from the heating curve, answer the analysis questions.
This activity with the heating curve data is available in a printable version.
Graph the Heating Curve of Water
Procedure
Use the data from the following table to produce a heating curve for water. Make sure your graph contains a title and labeled axes. Also, label the sections of the graph that represents water as solid, liquid, and gas.
