Answer this density question?

Question

Based on the diagram below, rank the three objects from LEAST dense to MOST dense.

X is floating on the very top
Y is floating just under the surface
Z is on the bottom of the beaker

* A. Object X, object Z, object Y.
* B. Object Z, object Y, object X.
* C. Object X, object Y, object Z.
* D. Object Y, object Z, object X.

Answer 1

It's C.



Objecs that are less dense float to the top.

Answer 2

The percentage of an object that is above the surface is related to its density. An object with a density of .5 kg/m^3 will have have of its volume floating and the other half in water. If the density is above 1 kg/m^3. Than it will sink. Thus C is the correct answer. X is least dense because it is floating the most. Z is the most dense because it is sinking.

Answer 3

B
