Viscosity of liquids decreases with increase of temprature. Why?

Text Solution

Verified by Experts

VIscosity of liquids decreases as the temperature rises because at high temperature molecules have high kinetic energy and can overcome the intermolecular forces to slip past one another between the layers.
