In determining the volume of the irregularly shaped object, any air bubbles sticking to the surface of the object when it is submerged cause systematic errors. Will this error give an experimental density that is too high or too low? Explain.

Problem 6

Archimedes, a famous Greek scientist, was given a problem by King Hieron II of Syracuse (Sicily). The king suspected that his crown, which was supposed to be made of pure gold, contained some silver alloy, and he asked Archimedes to prove or disprove his suspicion. (It turned out that the crown did contain silver.) How would you experimentally determined whether or not the crown was pure gold? (Hint: The method came to Archimedes when getting into a full bathtub. See the footnote in Experiment 22 for Archimedes' solution.)
