Question

Rosa fills a graduated cylinder with 100 milliliters of Liquid X. She fills another graduated cylinder with 100 milliliters of Liquid Y. Then, at the same time and from the same height, she drops a marble into each liquid. The marble hits the bottom of the cylinder containing Liquid Y first.
Which best explains this result?

Liquid X is more viscous than Liquid Y.
Liquid Y is more viscous than Liquid X.
Liquid X’s atoms have weaker attractive forces.
Liquid Y’s atoms have stronger attractive forces.

Answer 1

The answer is A, Liquid X is more viscous than Liquid Y.

Hope this helps!

Answer 2

The correct answer is option A Liquid X is more viscous than Liquid Y

When Rosa fills the cylinder with two different kinds of fluid and then drops a ball into the liquid.

The ball reaches the bottom of the liquid Y first as compared to the liquid X because the viscosity of the liquid X is more than the viscosity of the liquid Y.

Viscosity can be defined as the state of being thick, semi-fluid in consistency, stick, due to which a fluid has a ability to flow.
