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

Options

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

Answer

B

Explanation

When the temperature is raised, the viscosity of liquid decrease, this is because increasing in temperature increases the average kinetic energy of molecules which overcome the affractive force between them.
