Lab Report Coefficient of Linear Expansion of a Metal Introduction Most solid materials expand upon heating and contract when cooled because it undergoes a change in the energy state of its molecules or atoms. According to the atomic perspective, the average vibrational amplitude of an atom increases as the temperature rises.

Linear expansion is change in length due to change in temperature. In the experiment we are required to determine the coefficient of linear expansion of metal tube namely aluminum and copper.The purpose of this lab experiment is to measure the linear expansion coefficients of up to three different metals by observing how these materials expand and contract with changes in temperature. In addition, we will incorporate simple mathematical modeling techniques to fit curves to empirical data.Coefficients of Linear Thermal Expansion Linear temperature expansion coefficients for aluminum, copper, glass, iron and other common materials. Sponsored Links. When an object is heated or cooled, its length change by an amount proportional to the original length and the change in temperature.

In this experiment I studied the coefficient of linear expansion of various unknown metals and compared them to the known coefficients for several metals. The experiment was carried out using an apparatus into which two metal rods of approximately 1 meter in length could be clamped.

Read MoreThis experiment is done to determine the temperature coefficient of linear expansion of different materials. The different temperature coefficient is obtained through the use of an apparatus for measuring the linear expansion. The PASCO Thermal Expansion Apparatus was use to measure the thermal expansion to get the temperature coefficient.

Read MoreCONCLUSION I therefore conclude that all matter undergoes thermal expansion when subjected to change in temperature. Bridges and roads are some of those who experience this natural phenomenon. This experiment aims to find the factors affecting this property and also to determine the experimental value of coefficient of linear expansion. After determining the experimental coefficient linear.

Read MoreExper Linear Expansion Coefficient Theoretical consideration It is found that most solids expand when heated. The change in length, AL, of the solid is found to be directly proportional to the original length of the solid, Lo, and to the change in temperature, AT, of the solid.

Read MoreLinear Expansion. To a first approximation, the change in length measurements of an object (linear dimension as opposed to, for example, volumetric dimension) due to thermal expansion is related to temperature change by a linear expansion coefficient.It is the fractional change in length per degree of temperature change.
