Question

1. in determination of the volume of the irregularly shapedobject, any air bubbles sticking to the surface of the object whenit is submerged cause systematic errors. will this error give anexperimental density that is too high or too low? Explain. 2. Archimedes, a famous greek scientist, was given a problemby king hieron II of syracuse. The king suspected that his crown,which was supposed to be made of pure gold, contained some silveralloy, and he asked archimedes to prove or disprove his suspicion.(it turned out that the crown did contain silver.) how would youhave experimentally determined whether or not the crown was puregold? 1. in determination of the volume of the irregularly shapedobject, any air bubbles sticking to the surface of the object whenit is submerged cause systematic errors. will this error give anexperimental density that is too high or too low?

Explanation / Answer

(1) The bubbles will make the density of the object appearlighter because air has a lower density than H20 (2) One can detrmine the density of the crown by comparing theweight of the crown in air, then submerged in H20 let the weight in air be (w) and the weight in water be(w') to determine density, use w/(w-w')=density
