Question

The density of solid aluminum is 2.70 g/cm3. If a 1g piece of aluminum is dropped in a cup of water, what will happen to the aluminum? (The density of water is 1.00 g/cm3.) It will sink to the bottom. It will float to the top. It will hover in the middle. It will move up and down.

Answer 1

Answer:

The correct answer is: It will sink to the bottom

Explanation:

Density is the mass of substance per volume. If we compare the density value of water (1.00 g/cm³) and aluminum (2.70 g/cm³), we can see that:

density aluminum > density water

 (2.70 g/cm³)        >  (1.00 g/cm³)

Thus, when we put solid aluminum in a cup of water, the aluminum will have more weight than surrounding water, so it will drop to the bottom of the cup.
