Which substance has the highest viscosity?

Answer 1

This is a pretty vague question, and the answer would be it depends on many things. Are you including non-newtonian fluids? If so, it would be a non-newtonian fluid of some sort. Glass is actually a "supercooled liquid" and would have a very high viscosity if you include supercooled liquids.

It also depends on temperature. water at 1 degree Celcius has very low viscosity, but lowering it to 0, turns it into a solid

On the other end, there are a few man made substances with 0 viscosity, that will literally climb the walls of a container and coat it with a 1 atom thick layer

OMFG-OSH! i would say oil or something that's thick <--- lol THICK HE HE HEEE!

but to get to the point it'll be a hot substance that's oily or something in that manner.... hope i was a big help XD

Answer 2

For a substance to have a high viscosity, this means it must be heated and the particles get closer together and harder for one to flow past another, causing the substance to be thicker.Hope this helps

Answer 3

Viscosity is attributed to the cohesion of a liquid. Cohesion is the attraction between like molecules. This attraction comes from the type of bonds the molecule has. The three types are hydrogen bond, dipole force, and London forces.

Hydrogen bond- strongest type of intermolecular bond. Results from an O-H, N-H, of F-H bond. This is because the pulls are so strong by Oxygen, Nitrogen, and Fluorine on Hydrogen that it creates an almost ionic bond.

Dipole forces- next strongest type of IMF. results from unequal sharing in a bond.

London forces- weakest type of IMF. results from slight polarization in otherwise nonpolar molecules.

Answer 4

If the substance has weak intermolecular forces such as dipole-dipole or London dispersion it will have a low viscosity.
