Expansion Apparatus

Product Code : ILS-PLE-10218

Indian Lab Suppliers supplies the Expansion Apparatus (Product ID: 10218) as part of its physics lab equipment range. It shows the linear expansion of metal bars on heating by magnifying the movement with a pointer on a scale.

Quick Answer

Two cast iron uprights, 18 cm high, are joined by two nickel-plated rods. A 38 cm expansion bar is fixed to one upright and rests on a friction pointer at the other; as the bar expands it turns the pointer across a scale marked 0 to 90°. One bar each of brass, aluminium and iron is supplied so students can compare them: aluminium expands most, then brass, then iron.
