Thermal Expansion

Linear expansion of metals

Principle

Metal tubes are heated with steam. The linear expansion of three different metals is determined with the aid of a rotating-shaft pointer. From this the metals' coefficient of linear expansion is determined (Supplementary problem). The use of a rolling ...

Volume expansion of gases at constant pressure

Principle

A U-tube manometer with movable branches can be used to measure the expansion of gases at constant pressure. As the heated volume of air expands, the user slides the right branch until the water in the two branches reaches the same height again (p = const ...

Thermal expansion in solids and liquids

Principle

The volume expansion of liquids and the linear expansion various materials is determined as a function of temperature.

Tasks

1. To determine the volume expansion of ethyl acetate (C4H8O2), methylated spirit, olive oil, glycerol and water a ...
