what affect will adding sugar have on the viscosity of water
I think we can consider viscosity (resistance to flow) to be related to the forces holding the molecules of the liquid together. A more viscous fluid likely has stronger intermolecular forces. So then - to determine what happens to viscosity, we need to determine the effect on the intermolecular forces due to the addition of sugar. You may recall from chemistry that addition of a solute raises the boiling point of a fluid - this is indicative of greater intermolecular forces. So - we can say that adding sugar increases the intermolecular forces, raising water's viscosity. Consider, for example, the very viscous example of honey - what is honey other than a supersaturated solution of sugar? As a caveat - this is by no means a formal proof or answer; just the application of a bit of logic.
if the water is warm enough to melt sugar then the velocity is lowed because sugar makes the water thicker and the water changer a slight hint of yellow.
Thanks Guys!!!
lol thanks. well I saw those answers already. and I do get them, they are correct. But I guess what I'm really looking for is what would be the best hypothesis that I could use for this experiment. For some reason it's really difficult for me to think of a hypothesis. Please help, thanks.
Oh ok. How about this. I think that the more sugar you add than the higher the viscosity will be.
Does that sound good?
perfect, thank you soo much :) can't believe I didn't think of that.
Thanks! we all feel that way sometimes.
