Expansion of water.

Title: Expansion of Water Date: September 22, 2003 Purpose: This experiment is to find out whether water becomes more or less dense as it freezes. Procedure: 1. Insert the thermometer into one of the holes of the two-holed stopper and then insert the glass tube in the other. Glycerin will help the thermometer and tube to slide into the holes easily. 2. Fill the container to the top with water. 3. Holding the container upright, insert the stopper into the …

…water up and down the tube does not surprise me because I have seen another liquid move up and down a tube. An example of this is a thermometer. The liquid inside goes up and down according to the outside temperature. 3. The density of the water in the container would be largest at he 2-degree mark because it is measured at 3.7 cm on the ruler. That is the lowest it was during the entire experiment.
