Bar and Gauge Apparatus, Aluminium

Product Code : SCL-H-11848

Indian Lab Suppliers supplies the Bar and Gauge Apparatus, Aluminium (Product ID: 11848) as part of its heat and thermal physics range. This bar and gauge apparatus shows that a solid expands when heated and contracts when it cools.

Quick Answer

A metal bar on a rod with an insulated handle just fits the gap of a U-shaped gauge, also on an insulated handle, when both are cold. After the bar is heated in a flame it no longer fits; as it cools it slides in again. Hold both parts by the handles and let the bar cool before touching it.
