Question

How the viscosity of gases increases on increasing temperature?

Answer 1

In other words, increasing gas temperature causes the gas molecules to collide more often. This increases the gas viscosity because 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.
