Roy Lan #2 KTH 10/7/08 Introduction to Lab #2 In life, often are there three pillars of power that control a certain place or project. This is such in the case of this lab as well. The three pillars which this project is built upon are the properties of density, buoyancy, and lastly, the scientist and philosopher, Archimedes. We will start with density. Density if very important to the world today and to understand it you must first examine it from the beginning to the end. First, in order to find density you must know what density actually is. Oxford describes it as, “The degree of compactness of a substance; mass per unit volume or the quantity of people or things in a given area or space.” This is one of the most crucial steps needed in order to understand what density is. The Oxford translation is filled with many hard-to-learn vocabulary words so in other words, in my own words that is, density is the amount of atoms and such items contained within a certain object or amount of space. The equation to find density is actually very simple and easy to follow. The equation is mass over volume. The first component of this equation is obviously mass. Mass, in other words, is the weight of the object you are trying to examine. To find this you must weigh the object on some sort of scale of some kind or another. This is also an easy task to accomplish. The second part of the equation is made up of volume. Oxford defines volume as, “A book forming part of a work or series. A single book or a bound collection of printed sheets. A consecutive sequence of issues of a periodical. The amount of space occupied by a substance or object or enclosed within a container. The amount or quantity of something. Quantity or power of sound; degree of loudness. Fullness or expansive thickness of the hair.” Obviously you can discard any notion of some of these terms such as the volume of hair and the volumes of books. The volume that this

project is built upon is the one of space. Volume is how much space an object takes up and should not be confused with other measures of measurement such as mass. For instance, a normal sized computer takes up the same amount of space, as a small sized pillow yet doesn’t have the same mass as it. The difference between mass and volume is that volume is measured differently than mass. Mass is measured in either grams, pounds (America), or other types of measurements as so. While this is the case for mass, volume you measure the same way you do
