Q. How is the viscosity of a liquid varies when the temperature is raised?
Solution:
Viscosity of a liquid decreases when the temperature is raised.
The cohesive forces between molecules of liquids decrease as temperature increases. At high temperature the molecules of liquids have high energy and overcome strong cohesive forces and move freely. Hence , viscosity of liquids decreases with increase in temperature.
