Determination of Density for Regular and Irregular Objects
Abstract
The experiment in question would help in the understanding of the different ways in
which the density of the material can be determined. In the process the learner or anyone
interested would learn different methods applied in the determination of densities for different
shapes for instance regular and irregular objects. The objective is to help in the determination of
densities of various materials without any strain in the future (Watanabe and Tohma, et al 33).
To determine density of an object there is need for nondestructive physical process through
which various materials are distinguished from one another. It is sort of classification of
materials based on the understanding of their properties in relation to the primary aim which

in our case in density of regular and irregular objects. The laboratory experiment aims at
proving it right that the experimentation for density of materials applies in all cases and that no
material whether solid, liquid or gas lacks density.
Introduction
The aim of the experiment is to help in the understanding the meaning as well as the
importance of the significance that comes along with the density of substances. Density from the
theoretical understanding is a primary characteristic for homogeneous objects in their entirety. In
that regard we can say that density qualifies for intensive property, a property that that translates
to the meaning that density is dependent on the characteristics of the object in question in
terms of composition, size or amount in most cases. To determine density of an object there
should be first the nondestructive physical process through which various materials are
distinguished from one another (Watanabe and Tohma, et al 33). It is sort of classification of
materials based on the understanding of their properties in relation to the primary aim which
in our case in density of regular and irregular objects. The definition of density from the
formula point of view goes that density is the ratio of the objects mass (m) to its volume (V).
The SI unit for density in liquid or solid form is as follows g/mL or g/cm3 depending on
whether it is liquid or solid respectively. It should be noticed that cm3 is an equivalent to the mL
unit and no doubt about it should be made (Nikolić, Živković, Branković & Pavlović 559). The
units as put above work hand in hand and there should be no confusion about the use of the units.
In the experiment that is in question the main concern is the determination of the densities of
both regular and irregular objects putting more emphasis on the irregular object as the main
concern is how to accurately determine the density of the object that have undefined and
irregular size.

In this experiment focus would be on the determination of density of a liquid which is
defined in the procedure as water and use the same to compare the physical attributes or say
properties that the irregular object possess. Density is contained in the unit volume of any
object.
In as long as volume occupied by a gram water varies vary as temperature change, then
the density of the water for instance vary in accordance with the change in temperature. The
mass of the object in question would be attained in a different manner.
The mass is determined by the comparison of the mass of the object by the mass of said
known object. The mass in that regard is obtained through use of a weighing balance to be exact.
The volume for use in the experiment is obtained simply by use of a graduated measuring
cylinder, a graduated pipette or any other volumetric apparatus (Parihar, Anil Singh, et al). The
volume of a regular solid in most cases object like a spheres or cube is obtained by
measuring their dimensions then work out the volume through use of conventional
mathematical formulas.
There are some difficulties in the determination of the volume for irregular solids since
it is only obtained through use of the measure in the change in the water volume upon
immersing the object in water. The object in this regard displaces an equal volume of water in
accordance with the calibration (Wang, Yin, et al 379). The method however applies to
insoluble materials so in case the solid dissolves in water, then there should be in its place use a
liquid that the object in under study does not dissolve into for instance carbon tetrachloride if
the aim is to determine the volume of salt.

Theory and Objectives
In the event of determining density , mass and volume forms the most fundamental
part of the entire process. Mass and volume vary despite the similarity in the material used for
making the objects. Density comes in handy as it is the prevalent physical property for easier
characterization as well as classification of substances. It is important in that it applies in Quality
Monitoring and Process Control and for identity of heavier or lighter oil. The application of
density is vast as it cuts across various spheres of life be it environmental issues or
manufacturing life cycles in industries. The oil industry is however, the mostly affected with
expansive use of density and thus the emphasis on the determination of density of materials.
