An increase in temperature increases the average kinetic energy of molecules,which helps them overcome the attractive forces between them.

Vedclass · Answer

(B) Viscosity is a measure of the resistance of a liquid to flow,which arises due to the attractive forces between molecules. As the temperature increases,the average kinetic energy of the liquid molecules increases. This increased kinetic energy allows the molecules to overcome the intermolecular attractive forces that hold them together. Consequently,the liquid flows more easily,leading to a decrease in viscosity.

When the temperature is raised,the viscosity of a liquid decreases. This is because:
