For AS Level physics I had to do some coursework on the viscosity of Honey. I found out that as the temperature of the honey increases, its viscosity decreases.
I drew the conclusion that, when a substance is heated, its molecules move farther apart and faster, so therefore, if the molecules are moving farther apart, the substance will expand. This reduces the density of the Honey and lowers the viscosity, allowing the ball-baring to fall through the Honey faster.
However, I have been told this is not the actual reason for why the viscosity of the honey decreases, and that it has something to do with Helium atoms (in other words, ask a chemist).
Can anyone tell me why the viscosity decreases?
I’ve been stuck on this for a while and ill be grateful for any help.
Cheers,
