Question 1.
What happens to the viscosity of a liquid when its temperature increases?
Show hintHide hint
Think about molecular motion.
Question 2.
Do gases experience increased or decreased viscosity with rising temperature?
Show hintHide hint
Consider gas molecular activity.
3Question 3.
What effect does an increase in temperature have on the viscosity of liquids?
- Increases viscosity
- Decreases viscosity
- No effect
Show hintHide hint
Remember how heat changes fluid behavior.
4Question 4.
True or False: The viscosity of gases typically decreases with increasing temperature.
- True
- False
Show hintHide hint
Think of the kinetic energy in gases.
Question 5.
A fluid's viscosity at 25°C is 0.89 mPa·s. If its temperature is raised to 45°C, based on the Sutherland correlation, estimate the new viscosity assuming it behaves as a Newtonian fluid. Given constants a = 1.8, b = 0.54.

Ensure that you are using the absolute temperatures.
Question 6.
Describe a real-world scenario where understanding the difference in viscosity between a Newtonian and Non-Newtonian fluid could impact industry practices.
Show hintHide hint
Think about how texture impacts consumer experience.
