Increase in kinetic energy can overcome intermolecular forces of attraction. How will the viscosity of liquid be affected by the increase in temperature?
(i) Increase
(ii) No effect
(iii) Decrease
(iv) No regular pattern will be followed
The answer is the option (iii) Decrease
Explanation: Since kinetic energy increases with temperature, it can overcome intermolecular forces, and liquid starts flowing; hence the viscosity decreases.
