Linear expansion of solid bodies

Principle

A solid changes its geometrics under influence of heat, the effect is called heat expansion. In this experiment different metal tubes are heated with steam to investigate their linear expansion. The linear expansion is made visual by a rotating shaft with a pointer, over which the tube can glide. The expansion of different materials is compared.
