About This Product
As the bar is heated it lengthens, and because one end is held fixed, all the movement turns the friction pointer at the free end, giving a reading on the scale. Swapping between the brass, aluminium and iron bars lets students compare how much each metal expands. Colleges and TVET centres in Palestine, Seychelles, Papua New Guinea, Turkey, Morocco and South Korea can source the Expansion Apparatus from Educational Lab Equipments.
