When attempting to determine the composition of given objects,it is important to understand the physical properties such as mass, density,and volume. All matter has mass and in turn plays a role in the other twoproperties: density and volume. Volume is a necessary component to using thegas laws, density is the ratio of mass to volume. Density can also be viewed asthe amount of matter within a given space which aids in discovering the compositionof a given object.
It is important to understand these concepts before drawingany conclusions about the composition of separate objects to be studied. Finding the mass of any smaller object can be simplyachieved by the use of a balance. The factor of volume can be found in a coupledifferent ways and the procedure of this particular experiment utilized both.The simplest procedure involves immersing the object in water and calculatingthe difference in water level before and after immersion. The volume of an objectcan also be obtained by multiplying the length by width by height; or the useof the constant ? in the case of a cylinder, a sphere, or cone.
From thecombination of the two factors found, the density of the object(s) can bedetermined.
