About This Product
An expansion apparatus is used in physics to show that solids lengthen when heated and that different metals expand by different amounts. One end of the bar is held fixed while the other end moves a pointer across a scale, so the change in length can be seen and compared. With aluminium, brass and iron bars in the set, three metals can be tested in the same arrangement. Teachers use it when introducing thermal expansion of solids. School Lab Equipment India can export the Expansion Apparatus to education buyers in New Zealand, Bhutan, Mauritania, Venezuela and Mali.
