Origins of viscosity
Liquids
„ Short-range attractive intermolecular forces
Å  Hard to model exactly
Å  Described empirically
„ Viscosity usually decreases with increasing T
Gases
„ Momentum transfer between “ fast� and “ slow�
molecules
„ Simple kinetic theory gives a prediction
„ Predicts an increase with temperature
