Question
Chemistry Question on Liquid state
When the temperature is raised, the viscosity of liquid decreases this is because
A
decreased volume of the solution.
B
increased attraction between molecules.
C
decreased covalent and hydrogen bond forces.
D
increase in temperature increase the average kinetic energy of molecules which overcomes the attractive force between them.
Answer
increase in temperature increase the average kinetic energy of molecules which overcomes the attractive force between them.
Explanation
Solution
When the temperature is raised, the viscosity of liquid decreases, this is because increase in temperature increase the average kinetic energy of molecules which overcome the attractive force between them.
