Post-Lab Questions
1. What happens to the apparent weight when the objects are
submerged in water?

2. Use the value of the buoyant force to calculate an
experimental value of the volume of all of the objects in kg/m3 (Fb
=ρLVD
g). Show your work.

3. .png”>Use the measured dimensions of the 250 g mass to calculate
the volume of the mass, Show your work.

4. Determine the percent difference between the measured
volume of the 250 g mass and the value calculated from the buoyant force
measurement. Show your work.

5. Using the fact that 1 mL = 1 x 10-6 m3,
compare the volume of the displaced water to the calculated volume of the mass
from Post-Lab Question 3 with a percent difference calculation. Show your work.
6. Are the three experimental values of the volume of the 250
g mass (from Archimedesâ€™ Principle) larger or smaller than the calculated value
using the caliper measurements? Why? Which of the three values for volume is
more accurate? Which of the two experimental volumes are more accurate?
Explain.

7.
Use the experimental
weight and volume of the rubber stopper to calculate the density of the stopper
in kg/m3 using the equationρ = m/v. Show your work.

8. Research the density of rubber stopper on the internet and
compare your measured value of the density with the values listed online.

9. Does the data support Archimedesâ€™ Principle? Why or why
not?

10. Identify two possible sources of error in the experiment?
How could the procedure be revised to remove these potential errors?
