question_answer 1)

  Increase in kinetic energy can overcome inter molecular 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

Answer:

  (c) Intermolecular force of liquid decreases with increase intemperature, hence viscosity of liquid also decreases. However, some exceptions are there like liquid proteins, and liquid sulphur.
