text: In the case of gases, the viscosity increases with temperature because of the increased molecular activity at higher temperatures.
text: Viscosity increases with temperature for gases and decreases with temperature for liquids.
text: It’s easy to see one reason why the viscosity increases with temperature: from η = ( 1 / 3 ) n m l u , η is proportional to the average molecular speed u , and since this depends on temperature as 1 2 m u 2 ¯ = 3 2 k B T (if this is unfamiliar, be assured we’ll be discussing it in detail later), this factor contributes a T dependence.
