Thermal Expansion Apparatus


This apparatus measure easily the coefficient of linear expansion for steel, copper and aluminium.
It consists of the following components

  1. Three metal tubes
  2. A foam insulator to avoid heat loss at thermistor connection point
  3. Thermoplastic elastometer tubing with ¼ inch inside diameter

Other equipments which are required

  1. A source of steam or hotwater
  2. A digital meter to measure thermistor resistance
  3. A small object to raise the end of expansion base

Following experiment can be performed on the apparatus

  1. Measuring the coefficient of Linear Expansion for copper, Steel and Aluminium,
