Objective: Determine the coefficients of expansion for brass, steel and glass
If solid bodies are heated up, they generally expand to a greater or lesser degree. In this experiment,
hot water is allowed to flow through tubes made of brass, steel and glass. The expansion in their
length is measured using a dial gauge. The linear expansion coefficients for the three materials are
then calculated from the change in their length.
