Why does viscosity decreases with increase in temperature?

✒The increasing gas temperaturecauses the gas molecules to collide more often. This increases the gas viscositybecause the transfer of momentum between stationary and moving molecules is what causes gas viscosity.
✒As a liquid is heated, the viscosity decreases ... just the opposite effect as in gases.
