Increase in kinetic energy can overcome intermolecular forces of attraction. How will the viscosity of liquid affected by increase in temperature?
A
Increase
B
No effect
C
Decrease
D
No regular pattern will be followed.
Answer
Decrease
Explanation
Solution
: Viscosity of liquids decreases as the temperature rises because at high temperature, molecules have high kinetic energy and can overcome the intermolecular forces to slip past one anther between the layers.
