All liquid molecules possess kinetic energy by virtue of their motion. This motion leads to collision and hence causes evaporation only if it is able to overcome intermolecular forces of attraction.
Increae 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
Name two intermolecular forces that exist between HF molecules in liquid state.
