How was viscosity measured in the "Viscosity" lab?

directly with a viscosity meter

indirectly by measuring the distance a liquid flowed in a given time

indirectly by measuring the volume of honey

directly with a spring scale

The viscosity can be measured in viscosity lab indirectly by measuring the distance a liquid flowed in a given time.

Option B

Explanation:

Viscosity is the measure of drift velocity of any fluid. So depending upon viscosity, the thickness or the density of the fluid can be understood. A fluid with high density will be highly viscous in nature and so that fluid will be flowing slowly.

In lab, we can measure the viscosity by measuring the distance a liquid flowed in a given time. If the viscosity of fluid is high, then that fluid will be taking more time to cross the given distance. And if the fluid is having less viscosity then, the liquid will be flowed easily.

the answer is d. 74.02

qualitative observation deals with data that can be observed with our senses: sight, smell, touch, taste, and hearing. they do not involve measurements or numbers. for instance, colors, shapes, and textures of objects are all qualitative observations.
