Principle
Using water as a model the expansion of a liquid is shown as a function of temperature. In the supplementary problem, the expansion coefficient is calculated at different temperatures. The expansion of water is not linear; its coefficient is not constant.
If you wish to demonstrate a liquid with a linear expansion coefficient, we recommend alcohol. However, it is very inflammable: be extremely careful when doing experiments with it!
