A liquid has a high normal boiling point. Will its viscosity and surface tension values be high or low?

Text Solution

Verified by Experts

The high normal boiling point of a liquid indicates that the liquid possesses strong intermolecular forces of attraction. The values of viscosity and surface tension of a liquid depend upon the strength of intermolecular attractive forces in the liquid. the stronger the intermolecular attractive forces, the higher the values of viscosity and surface tension of the liquid. as the intermolecular forces of attraction are strong for the concerned liquid, the values of both surface tension and viscosity of the liquid will be high.
