Example - water is a liquid where the volumetric expansion coefficient changes a lot with temperature. Water has its highest density and smallest volume at 4oC (39.2 oF). The volumetric coefficient for water is negative below 4oC and indicates that the a volume decreases when temperature moves from 0oC (32 oF) to 4oC.
