Just given in my physics Coursework and I wanted to see what you lot thought about my rather interesting results. Basically, I compared the vicosity and surface tension of both water and glycerol through a series of tests and was rather surprised at what I found. According to my results (and data books when I checked), water has a higher surface tension than glycerol, but glycerol is more viscous than water. Everything I have read on the internet and heard from Chemistry teachers is that both viscosity and surface tension are directly proportional to the amount of hydrogen bonds a molecule has, but obviously that cannot be the whole truth. Any thoughts on this?
