When the temperature is raise, the viscosity of liquid decreases, this is because,

Options

A. Decreased volume of the solution
B. Increase in temperature increases the average kinetic energy of molecules, which overcome the attractive force between them
C. Decreased covalent and hydrogen bond forces
D. Increased attraction between molecules

Answer

B

Explanation

When the temperature is raised, the viscosity of liquid decreases, this is because increase in temperature increases the average kinetic energy of molecules which overcome the attractive force between them.
