Question

How does viscosity of fluid and gas vary with temperature?

Answer 1

Higher the temperature, lesser is the cohesion so viscosity decreases. Viscosity of gases depends on the molecular momentum transfer. Higher the temperature, more energy possessed by the molecules and thus greater the momentum of colliding gas molecules. Thus viscosity increases with increases in temperature for gases.
How do the viscosities of liquid

Answer 2

HEY BUDDY HERE IS UR ANSWER !!

Viscosity of liquids depends on the cohesive force. Higher thetemperature, lesser is the cohesion so viscosity decreases. Higher the temperature, more energy possessed by the molecules and thus greater the momentum of colliding gas molecules. Thus viscosity increases with increases intemperature for gases.
