Problem
Are additional hydrogen bonds formed when water and glycerol are mixed?

Prediction
I predict that additional hydrogen bonds will not form, and there will be little or no heat produced.

Design
On Sheet

Materials
On Sheet

Procedure
On Sheet

Evidence
The temperature of the distilled water was 21 degrees Celsius. The temperature of the Glycerol was also 21 degrees Celsius. When mixed, the product was 23 degrees, two degrees above the temperature of either the other materials.

Analysis
There was a slight increase in temperature, and so there was probably some hydrogen bonds forming. My prediction was wrong, although the margin of temperature increase was still very slight.

Evaluation
The test was not as secure as I would have liked it. Also, I think I had a misunderstanding; a hydrogen bond would produce a lot of heat, I thought.
