Source sentences:
text: In principle, thermometers made of different material (e.g., coloured alcohol thermometers) might be expected to give different intermediate readings due to different expansion properties; in practice the substances used are chosen to have reasonably linear expansion characteristics as a function of true thermodynamic temperature, and so give similar results.
text: Before the discovery of the true thermodynamic temperature, the thermometer defined the temperature; thermometers made with different materials would define different temperature scales (
