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