Final Exam Practice Quiz

A team of students make a boat out of a piece of aluminum foil. The boat floats on the water while holding 11 pennies. The picture shows the design of the boat.

• The boat floats because the aluminum in the boat is more dense than the water.

• The boat floats because the water is more dense than the metals in the pennies.

• The boat floats because the density of the boat is less than the density of the water.

• The boat floats because the density of the water is less than the density of the pennies.

Emily conducts an experiment to compare the densities of cork and iron with water. She places a piece of cork and a small iron nail in a beaker filled with 100 mL of water, and she records her observations. 1. The piece of cork floats on water. 2. The iron nail sinks to the bottom of the beaker. What can Emily conclude from her experiment?

• Both the cork and the iron nail are more dense than water.

• Both the cork and the iron nail are less dense than water.

• The cork is more dense than water, and the iron nail is less dense than water.

• The iron nail is more dense than water, and the cork is less dense than water.
