  • When the temperature is raised the viscosity of the liquid decreases. This is because of

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