Density changes in water
The density changes which occur when a piece of ice at – 10°C is gradually heated up to 100°C are shown in Fig. 15.14. The maximum density region on this graph should be compared with the corresponding volume changes shown in Fig. “15.13. Note how much greater is the density change when ice melts to form water at 0 °C compared with the density change of water between 0 °C and 4°C.
