An egg is placed at the bottom of a bowl filled with water.Salt is slowly added to the water until the egg rises and floats.From this experiment,we conclude that
A)egg-shell calcium is repelled by sodium chloride.
B)the density of salt water exceeds the density of the egg.
C)buoyant force is not always exerted upward.
D)salt sinks to the bottom.
E)none of the above

Question

Quizplus · Accepted Answer

As salt is added to the water, the overall density of the water increases. Eventually, the density of the salt water exceeds the density of the egg, causing it to float to the top. This experiment demonstrates the principle of buoyancy and how the density of an object impacts whether it will float or sink in a fluid. None of the other answer choices accurately explain the phenomenon observed in this experiment.
