The force of gravity pulls liquid
avity pulls liquid to the bottom of any container.
Why did the author include this idea?
(A)
to explain why liquids take the shape of any container.
(B)
to explain how gravity works using liquid as an example.
(C)
to highlight how gravity has a greater,
me now gravity has a greater effect on liquids than on other phases of matter.
(D)
to highlight how important gravity is in the formation of phases of matter.
