How does the coefficient of viscosity of a liquid and a gas depend on temperature?

(N/A) The coefficient of viscosity of a liquid decreases,while that of a gas increases,with an increase in temperature.
This difference arises because the mechanism of viscosity in gases is based on molecular momentum exchange,whereas in liquids,it is based on cohesive forces.
$\Rightarrow$ In gases,an increase in temperature leads to higher molecular kinetic energy and increased molecular momentum exchange,which results in an increase in viscosity.
$\Rightarrow$ In liquids,an increase in temperature weakens the intermolecular cohesive forces,which leads to a decrease in viscosity.
