Page 4: Introduction
The PASCO Model TD-8579A differs from the previous model TD-8578 in that it uses a Rotary Motion Sensor instead of a dial gage for measuring length changes in the rod, a Thermistor Sensor instead of an ohmmeter, and is compatible with a ScienceWorkshop®... -

Sensor connecting Thermistor Sensor (CI-6527A) Additional Equipment Required In addition to the TD-8579A Thermal Expansion Apparatus, you need the following items to perform the experiment, which is described on pages 5-6 of this manual: • ScienceWorkshop Interface (500, 700 or 750) •... -
Page 6: Apparatus Setup
012-07599C Computer-based Thermal Expansion Apparatus Apparatus Setup 1. Attach the Rotary Motion Sensor (RMS) to lug underneath the capture spring to attach the the large end block on the apparatus. Use thermistor lug beneath the clamp. the black thumb screws to attach the RMS to the holes in the larger of the black end blocks (See Figure 1). -

Computer-based Thermal Expansion Apparatus 012-07599C Experiment Setup Calibration The Thermistor Sensor and Rotary Motion Sensor are both factory-calibrated and do not require additional calibration. However, if you wish to calibrate the Thermistor Sensor, you may do so. For calibration instruc- tions, see the DataStudio (version 1.5.2 or later) online help. -
Page 8: Experiment: Measuring The Coefficient Of Linear Expansion For Copper
012-07599C Computer-based Thermal Expansion Apparatus Experiment: Measuring the Coefficient of Linear Expansion for Copper, Brass, and Aluminum Introduction Most materials expand when heated through a temperature range that does not pro- duce a change in phase. The added heat increases the average amplitude of vibration of the atoms in the material, which increases the average separation between the atoms. - Page 9 Computer-based Thermal Expansion Apparatus 012-07599C Experiment (Continued) Cut and place the plastic tubing over both tube ports on top of the lid covering the Steam clamp Generator (See Figure 3). [Note: Cut the tubing enough to allow it to reach the rod on the apparatus, but keep the tubing as short as possible, to prevent kinks and maximize rapid STEAM...

012-07599C Computer-based Thermal Expansion Apparatus Data and Calculations 1. In DataStudio, from the Digits display, record the maximum length change (delta ∆L) and the temperature change (∆T) for each rod. Record your results in Table 1. 2. Using the equation ∆L = αL ∆T, calculate α for copper, brass, and aluminum. Record your results in Table 2. -

Computer-based Thermal Expansion Apparatus 012-07599C Sample Data The following are examples of data obtained using DataStudio™, a ScienceWorkshop® 750 Interface and the TD-8556A Steam Generator. The data will vary according to experimental conditions, setup modifications, temperature of the heat source, type of experiment, temperature units (degrees K, F, or C), etc. -
Page 12: Troubleshooting
012-07599C Computer-based Thermal Expansion Apparatus Troubleshooting Problem: During the experiment, temperature measurements do not appear in an open DataStudio display. Solution(s): a) Ensure that all connections between the Thermistor lug and rod, and Thermistor Sensor and ScienceWorkshop interface are tight. (See Apparatus Setup on page 3 for instructions). b) In DataStudio, double click on the Thermistor icon. -
