Question

An object was dropped into a glass of water and settled at the bottom of the glass. Later, the object was dropped into a glass of oil, but this time the object floated. Can you explain why it sank in water but floated in oil?

A. Oil is denser than water.
B. The object is less dense than oil.
C. The object is more buoyant in oil.
D. The object underwent a chemical change.

Answer 1

The object sank in water because it is denser than water. However, it floated in oil because oil is less dense than water.

Step-by-step explanation:

The object sank in water because it is denser than water. When an object is denser than the fluid it is placed in, it will sink. However, when the object was dropped into the glass of oil, it floated because oil is less dense than water. Objects that are less dense than the fluid they are placed in will float.
