The measurement of changes with time in the volume, length, width, or thickness of a material sample caused by temperature changes under negligible load or by chemical reaction.
Notes:
- One-dimensional changes are often measured using mechanical displacement detection. Volume changes are often determined using an inert confining liquid, for example, mercury.
- Measurement of an applied hydrostatic pressure allows the determination of pressure–volume–temperature (\(p,V,T\)) diagrams.
- A polymerisation reaction is an example of a chemical reaction that can be studied using a dilatometer.
