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.

Explanation:

Step1: Compare densities

The density of aluminum is $
ho_{aluminum}=2.70\ g/cm^{3}$ and the density of water is $
ho_{water} = 1.00\ g/cm^{3}$. Since $
ho_{aluminum}>
ho_{water}$.

Step2: Determine behavior

Objects with density greater than the liquid they are in will sink. So the aluminum will sink to the bottom.

Answer:

It will sink to the bottom.
