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.

### What students are saying

• As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

• I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

• The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
