Instruction manual and experiment guide for the PASCO TD-8558A Thermal Expansion Apparatus, covering setup, measurement procedures, and data calculations.
This document serves as an instruction manual and experiment guide for the PASCO scientific Model TD-8558A Thermal Expansion Apparatus. It details the equipment included, such as the expansion base with a built-in dial gauge and thermistor, and three metal tubes made of steel, copper, and aluminum. The guide explains how to measure the coefficient of linear expansion for these materials by passing steam or hot water through the tubes and recording the resulting expansion and temperature changes.
| Dial Gauge Resolution | 0.01 mm |
|---|---|
| Temperature Measurement Accuracy | 0.5 °C |
| Tube Length | 70 cm |
| Warranty Period | one year |
The apparatus allows for measurements of the coefficient of linear expansion for copper, steel, and aluminum.
The resistance is converted to temperature using the conversion table provided on the expansion base and the back page of the manual.
