    Viscosity
In summary, viscosity is a measure of a fluid's resistance to flow and is important because it can affect industrial processes and product performance. It is typically measured using a viscometer, and factors such as temperature, pressure, and impurities can affect it. High and low viscosity fluids include honey and water, respectively, and viscosity can impact the flow and consistency of a fluid.

The question is attatched. The question is number 8.

I simply do not understand, if the question is right at all, because I believe that options A and D are both correct. But, B it seems is the answer. High temp means low visc. and vice versa, leading to A and D being correct.

Please explain why B is correct

Low viscosity means higher terminal velocity. (Less resistance)
High viscosity means lower terminal velocity.
Only one option can be right.
 

What is viscosity and why is it important?

Viscosity is a measure of a fluid's resistance to flow. It is important because it affects the efficiency of many industrial processes and can also impact the performance of various products.

How is viscosity measured?

Viscosity is typically measured using a viscometer, which measures the time it takes for a fluid to flow through a specific tube or opening. The longer the flow time, the higher the viscosity.

What factors can affect the viscosity of a fluid?

Temperature, pressure, and the presence of impurities can all affect the viscosity of a fluid. In addition, the type and concentration of particles or molecules in the fluid can also impact its viscosity.

What are some examples of high and low viscosity fluids?

High viscosity fluids include honey, motor oil, and molasses, while low viscosity fluids include water, gasoline, and rubbing alcohol.

How does viscosity impact the flow of a fluid?

Higher viscosity fluids flow more slowly and have a thicker consistency, while lower viscosity fluids flow more quickly and have a thinner consistency. This can affect the ease of movement and stability of the fluid.
