2) A glass sphere and a lead sphere have the same volume. Each sphere is dropped into a container of water. Which statement best explains why the lead sphere settles faster?

A. The lead sphere has a higher density.
B. The glass sphere has a smoother surface.
C. The lead sphere takes up less space.
D. The glass sphere has more surface area.



Answer :

Final answer:

The lead sphere settles faster due to its higher density compared to the glass sphere.


Explanation:

The statement that best explains why the lead sphere settles faster is:

  1. A) The lead sphere has a higher density.
    Because density is mass per unit volume, the lead sphere, having a higher density than the glass sphere, will sink faster in water since it weighs more per unit volume.
