Changes

One problem that arose during this experiment was the difficulty in maintaining the proper temperature for the water. The hot plate did not accurately represent the temperature of the water in the vials, so a third vial was set up with a thermometer inside to properly gauge the water temperature. However, despite this, the temperature still varied throughout the experiment. At some point on May 2nd, Jim had noticed that the vials were bubbling and checked the temperature to be greater than 180 deg F and closer to 200 deg F which may have caused a difference.

Another problem worth noting was that the 180 deg F fibers were arced, which may be due to the fact that they naturally rested on the bottom of the vials on the hot plate, so one side of the fibers possible got hotter and therefore expanded more than the other side, causing the fibers to bow. Because of this, I believe Ann Marie and I will be doing more heat tests.
