Editing Chemical polarity (section)

===Viscosity===
Polar liquids have a tendency to be more [[Viscosity|viscous]] than nonpolar liquids.{{cn|date=May 2023}} For example, nonpolar hexane is much less viscous than polar water. However, molecule size is a much stronger factor on viscosity than polarity, where compounds with larger molecules are more viscous than compounds with smaller molecules.{{cn|date=May 2023}} Thus, water (small polar molecules) is less viscous than hexadecane (large nonpolar molecules).
