When water is heated under atmospheric pressure, two things occur. One is a change in temperature. The other is a change in phase. These two properties will be studied to determine the heat of fusion and the heat of vaporization of water.

A black wood top or a plastic top can be placed on each table. Use the thin metal rods from D89 and the triangular ring stands by the ice machine / S155.
Make sure that the room has plenty of paper. Leave out a matter model (with the springs) on the table of the lab instructor. Fill the two coolers with ice. Ice must be acquired near classtime from friends in the Biology or Chemistry Departments. If you cannot be present to get ice nor arrange for someone else to, please inform the instructor as soon as possible.
Along with the initial apparatus set-up, supply a sufficient number of the appropriate paper procedure handouts for all of the lab sections that will use the set-up over the course of the week. Print the PDF, duplicate to double-sided pages, staple, and leave pile on instructor's table prior to first use of set-up.
