Question

Grace is given a piece of wood, an iron nail, and a styrofoam cup. She puts these objects into a bucket of water and observes that the nail sinks to the bottom, the wood floats just under the surface, and the cup floats on top of the water. What property is being demonstrated by this experiment.

Answer 1

density if u in k12 there is page on each test that give u the answer just saying for people in k12

Answer 2

Explanation:

Density is defined as the degree of compactness or mass per unit volume.

Mathematically,         density = $\frac{mass}{volume}$

It can be seen from the formula that mass is proportional to density. That is, more is the mass of an object more will be its density.

Therefore, it is given that iron nail sinks to the bottom this means that the iron nail has highest density as compared to the piece of wood and a styrofoam cup.

Thus, we can conclude that given experiment demonstrates the density of given objects.
