Most of the time the molecules in gas are flying free through the void.
when temperature is increased the collision of the molecules increase which decreases the ability of the molecules as a whole to engage in the co-ordinated move.
So, when the gas gets hotter they get thicker.
The viscosity of the gas increases as temperature Increases as is approximately proportional to the square root of temperature.

We know that, density of gas (ρ) = PM / RT
Therefore, as temperature increases density of the gas decreases.
But see density and viscosity are not interrelated at all!
For gas, it must be explained by Kinetic Theory. With an increase in temperature, there is typically an increase in the molecular interchange as molecules move faster in higher temperatures. The gas viscosity will increase with temperature. According to the kinetic theory of gases, viscosity should be proportional to the square root of the absolute temperature, in practice, it increases more rapidly.
But if the temperature of gas exceeds the ionization temperature, the viscosity will be reduced. for example >10000 K for Ar.
