Purpose The purpose of this lab is to use direct measurement and Archimedes’ principle to determine the density of a number of different solids and liquids. Theory The density of a substance is defined by Density = m/V where m is the mass and V is the volume. The buoyant force exerted by a fluid on an object is defined by F B = m fluid displaced * g = Density fluid V fluid displaced * g Where m is the mass of the fluid displaced, g is gravity, and V is the volume of the fluid displaced. F apparent weight = (Density object – Density fluid ) * V * g Where V is the volume of the fluid and g is the gravity. Procedure We began the experiment with the direct measurement method for the density of a solid. We filled the overflow can with water up to the point before water spilled out of the spot. We placed a calibrated beaker underneath the spout and lowered a metal block into the water. As water was forced out of the spout and into the calibrated beaker, we could measure how much water was displaced by the metal block. We repeated the
