2. Ice is able to float on water because the ice is
- A. colder than water.
- B. denser than water.
- C. has a greater mass for the same volume of water.
- D. has a greater volume for the same mass of water.
Answer: D. has a greater volume for the same mass of water.
Answer: D. Ice takes up more volume for the same mass, so it is less dense than water and floats.
Answer: D. Ice takes up more volume for the same mass, so it is less dense than water and floats.
