The density of solid aluminum is 2 point 7 0 the fraction with numerator g and denominator cm cubed If a 1 g piece of aluminum is dropped in a cup of water, what will happen to the aluminum? (The density of water is 1 point 0 0 the fraction with numerator g and denominator cm cubed )
Answer
A
It will hover in the middle.
B
It will sink to the bottom.
C
It will float to the top.
D
It will move up and down.
Explanation
An object sinks in water when its density is greater than water’s density. Aluminum has a density of 2.70 g/cm³, which is greater than water’s 1.00 g/cm³, so the aluminum will sink to the bottom.
