Water thermometer

(definition) by Webster 1913 Wed Dec 22 1999 at 4:21:42

Wa"ter ther*mom"e*ter (?). Physics

A thermometer filled with water instead of mercury, for ascertaining the precise temperature at which water attains its maximum density. This is about 39° Fahr., or 4° Centigrade; and from that point down to 32° Fahr., or 0° Centigrade, or the freezing point, it expands.
