Question

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

  1. Decreased volume of the solution   
  2. Increase in temperature increases the average kinetic energy of molecules, which overcome the  
  3. Decreased covalent and hydrogen bond forces  
  4. Increased attraction between molecules  

The correct answer is: Increase in temperature increases the average kinetic energy of molecules, which overcome the


    between them
