Ice does not have negative expansivity. Transition from liquid water to water ice shows increase of volume, but as phase transition I do not think it qualifies. Water from 0 to 3.983 C does however increase in density as function of temperature.
- Actually, ice does show NTE in its hexagonal and cubic phases at very low temperatures (below -200 °C). Spute 20:41, 2 February 2007 (UTC)
