Objective: The purpose of this lab was to determine the density of five solid objects (Aluminum bar, Copper, gold, silver cylinders and feldspar mineral). To determine the density, one must find out the mass by weighing the object, as well as the volume, by measuring the dimensions and by finding the displacement which is the measurement based on displacement of water. Physical principles: The purpose of this experiment is to obtain density results of solid objects. Density is defined as the mass per unit volume occupied by an object or substance. In the metric system, theunit of density for a liquid or solid is measured in g/cm^3. Density is an intensive property. Intensive properties are those that are held constant no matter what the quantity of the sample being taken. Mass and volume, which are units used to determine density are crucial properties due to them changing and contributing with the quantity of the samples. To determine the mass of an object one must weigh the object on a scale and report the mass in grams. One can find the volume of an object in one of two ways. One can multiple the dimensions together (length x width x height), or use the water displacement method to determine the volume. To do so you
