When the temperature is raised, viscosity o the liquid decreases. This is because

A

decreased volume of the solution

B

increase in temperature increases the average kinetic energy of molecules which overcomes the attractive force between them

C

decreased covalent and hydrogen bond forces

D

increased attraction between the molecules

Text Solution

Verified by Experts

The correct Answer is:
B
With increase in temperature, viscosity of liquid decrease as the average kinetic energy of the molecules increases
