Various thermophysical variables are described on the following pages. The facilities and options available to measure thermophysical material properties within the working group can be downloaded as tables in pdf format.
The thermal expansion
The thermal expansion of a solid is a function of temperature. The linear expansion coefficient α at constant pressure p is calculated with:
dabei ist l0 whereby l0 is the length of the sample at a defined reference temperature, e.g. 273.15 K.
