Question:
Increase in kinetic energy can overcome intermolecular forces of attraction. How will the viscosity of liquid be affected by the increase in
temperature?
(a)Increase
(b)No effect
(c) Decrease
(d) No regular pattern will be followed
Solution:
(c) Intermolecular force of liquid decreases with increase in temperature, hence viscosity of liquid also decreases. However, some exceptions are
there like liquid proteins and liquid sulphur.
