The transition can be detected as a marked change in the thermal expansivity and heat capacity of the material.    From Wordnik.com.  [Archive 2005-09-01] Reference

Water's thermal expansivity increases with increased pressure.    From Wordnik.com.  [Citizendium, the Citizens' Compendium - Recent changes [en]] Reference

Water has a low coefficient of expansion (thermal expansivity).    From Wordnik.com.  [Citizendium, the Citizens' Compendium - Recent changes [en]] Reference

I work on materials with negative Poisson's ratios (NPR) and negative thermal expansivity.    From Wordnik.com.  [iMechanica - Comments] Reference

Water's thermal expansivity reduces increasingly (becoming negative) at low temperatures.    From Wordnik.com.  [Citizendium, the Citizens' Compendium - Recent changes [en]] Reference

Such fibres may acts as balancing plies during manufacture because they may effectively reduce thermal expansivity (see recent papers and patents by.    From Wordnik.com.  [iMechanica - Comments] Reference
