Why Does The Viscosity Of A Gas Generally Decrease With Decreasing Temperature Whereas For A Liquid Its Viscosity Generally Increases? [Solved]

The viscosity of liquids decreases with temperature, whereas the viscosity of gases increases with temperature. This is because in a liquid the molecules possess more energy at higher temperatures, and they can oppose the large cohesive intermolecular forces more strongly.
