To do the linear thermal expansion experiment, click the linear icon. 3. Select Aluminum for trial 1 f 4. Set the initial temperature of the rod to room temperature. (24 0C to 28 0C). 5. Increase the temperature of the rod by adjusting the final temperature icon. Set the temperature close to the boiling temperature of water. (95 0C to 100 0C).
filexlib. An important part of understanding sea-level rise is understanding thermal expansion of water. Students build a model using everyday items to demonstrate that water expands when heat energy is added. The background information section includes graphs of NASA satellite data for Sea Level and Global Temperatures, as well as links to these data sets.
This document introduces the Thermal Expansion Experiment from the Physics laboratory at the University of Toronto. It is intended to be used before you begin the experiment. The Preparatory Questions at the end of this document should be answered and turned in to your Demonstrator before you begin to work on the experiment. Requirements
According to experiments, the dependence of thermal expansion on temperature, substance, and original length is summarized in the equation. (1.4.1) d L d T = α L. where L is the original length d L d T is the change in length with respect to temperature, and α is the coefficient of linear expansion, a material property that varies slightly
With each corresponding vibrational energy level, the atom vibrates about an equilibrium spacing, which minimizes the free energy of the system. This equilibrium spacing increases with vibrational (a.k.a. kinetic energy), which is proportional to temperature – thus, thermal expansion! Note that the “<>” brackets indicate the average kinetic Thermal Expansion Apparatus 012-04394C 2 Accepted Values for Coefficient of Thermal Expansion Material a ( x10-6/∞C ) Copper 17.6 Steel 11.3 to 13.5 Aluminum 23.4 Changing Tubes Caution: When changing tubes be careful not to pull the wires off the thermistor. The thumb-screw must be com-pletely removed before the thermistor can be lifted off
Thermal Expansion Of Solids In physics, Thermal expansion can be defined as the change in the length, width, height, or volume of any material on changing the temperature. Thermal expansion is very evident in solids as atoms are densely packed. Thermal expansion of solids has loads of applications in day to day life. Table of Contents

measuring the thermal expansion coefficient. The Lab In the experiment, you will measure the change in length of a rod of aluminum and one of copper as a function of temperature. The heating will be accomplished by flowing steam around the rod. There is a provision for measuring the temperature of the rod while simultaneously measuring its length.
Thermal expansion for 14-16 These experiments will show the following facts. Solids expand very little when heated. Liquids expand a little more than solids (for the same volume). Gases expand a great deal when heated. Inside a fixed container they will increase in pressure. Up next Expansion of a solid rod Phase Change Properties of Matter
Thermal Expansion: Expansion Coefficients, Thermal Stress, Strain The tendency of matter to change its shape, area, volume, and density with a change in temperature is called Thermal Expansion. When most substances are heated, their molecules begin to vibrate and move creating more distance between themselves.
What is Thermal Expansion. Thermal expansion is the phenomenon observed in solids, liquids, and gases. In this process, an object or body expands on the application of heat (temperature). Thermal expansion defines the tendency of an object to change its dimension either in length, density, area, or volume due to heat.

Factors affecting THERMAL EXPANSION 5. Temperature • Higher change in temperature, the higher the expansion • ΔT for the symbol 6. Kind of Material • Quantified by a constant value for coefficient of thermal expansion for some materials • The higher the coefficient, the higher the expansion • Symbol used – α 7.
